# Britain (United Kingdom) and Ireland (Eire) 
 
# From Peter Ilieve (1994-07-06): 
# 
# On 17 Jan 1994 the Independent, a UK quality newspaper, had a piece about 
# historical vistas along the Thames in west London. There was a photo 
# and a sketch map showing some of the sightlines involved. One paragraph 
# of the text said: 
# 
# `An old stone obelisk marking a forgotten terrestrial meridian stands 
# beside the river at Kew. In the 18th century, before time and longitude 
# was standardised by the Royal Observatory in Greenwich, scholars observed 
# this stone and the movement of stars from Kew Observatory nearby. They 
# made their calculations and set the time for the Horse Guards and Parliament, 
# but now the stone is obscured by scrubwood and can only be seen by walking 
# along the towpath within a few yards of it.' 
# 
# I have a one inch to one mile map of London and my estimate of the stone's 
# position is 51 deg. 28' 30" N, 0 deg. 18' 45" W. The longitude should 
# be within about +-2". The Ordnance Survey grid reference is TQ172761. 
# 
# [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.] 
 
# From Paul Eggert (1993-11-18): 
# 
# Howse writes that Britain was the first country to use standard time. 
# The railways cared most about the inconsistencies of local mean time, 
# and it was they who forced a uniform time on the country. 
# The original idea was credited to Dr. William Hyde Wollaston (1766-1828) 
# and was popularized by Abraham Follett Osler (1808-1903). 
# The first railway to adopt London time was the Great Western Railway 
# in November 1840; other railways followed suit, and by 1847 most 
# (though not all) railways used London time.  On 1847-09-22 the 
# Railway Clearing House, an industry standards body, recommended that GMT be 
# adopted at all stations as soon as the General Post Office permitted it. 
# The transition occurred on 12-01 for the L&NW, the Caledonian, 
# and presumably other railways; the January 1848 Bradshaw's lists many 
# railways as using GMT.  By 1855 the vast majority of public 
# clocks in Britain were set to GMT (though some, like the great clock 
# on Tom Tower at Christ Church, Oxford, were fitted with two minute hands, 
# one for local time and one for GMT).  The last major holdout was the legal 
# system, which stubbornly stuck to local time for many years, leading 
# to oddities like polls opening at 08:13 and closing at 16:13. 
# The legal system finally switched to GMT when the Statutes (Definition 
# of Time) Act took effect; it received the Royal Assent on 1880-08-02. 
# 
# In the tables below, we condense this complicated story into a single 
# transition date for London, namely 1847-12-01.  We don't know as much 
# about Dublin, so we use 1880-08-02, the legal transition time. 
 
# From Paul Eggert (2003-09-27): 
# Summer Time was first seriously proposed by William Willett (1857-1915), 
# a London builder and member of the Royal Astronomical Society 
# who circulated a pamphlet ``The Waste of Daylight'' (1907) 
# that proposed advancing clocks 20 minutes on each of four Sundays in April, 
# and retarding them by the same amount on four Sundays in September. 
# A bill was drafted in 1909 and introduced in Parliament several times, 
# but it met with ridicule and opposition, especially from farming interests. 
# Later editions of the pamphlet proposed one-hour summer time, and 
# it was eventually adopted as a wartime measure in 1916. 
# See: Summer Time Arrives Early, The Times (2000-05-18). 
# A monument to Willett was unveiled on 1927-05-21, in an open space in 
# a 45-acre wood near Chislehurst, Kent that was purchased by popular 
# subscription and open to the public.  On the south face of the monolith, 
# designed by G. W. Miller, is the the William Willett Memorial Sundial, 
# which is permanently set to Summer Time. 
 
# From Winston Churchill (1934-04-28): 
# It is one of the paradoxes of history that we should owe the boon of 
# summer time, which gives every year to the people of this country 
# between 160 and 170 hours more daylight leisure, to a war which 
# plunged Europe into darkness for four years, and shook the 
# foundations of civilization throughout the world. 
#       -- <a href="http://www.winstonchurchill.org/fh114willett.htm"> 
#       "A Silent Toast to William Willett", Pictorial Weekly 
#       </a> 
 
# From Paul Eggert (1996-09-03): 
# The OED Supplement says that the English originally said ``Daylight Saving'' 
# when they were debating the adoption of DST in 1908; but by 1916 this 
# term appears only in quotes taken from DST's opponents, whereas the 
# proponents (who eventually won the argument) are quoted as using ``Summer''. 
 
# From Arthur David Olson (1989-01-19): 
# 
# A source at the British Information Office in New York avers that it's 
# known as "British" Summer Time in all parts of the United Kingdom. 
 
# Date: 4 Jan 89 08:57:25 GMT (Wed) 
# From: Jonathan Leffler 
# [British Summer Time] is fixed annually by Act of Parliament. 
# If you can predict what Parliament will do, you should be in 
# politics making a fortune, not computing. 
 
# From Chris Carrier (1996-06-14): 
# I remember reading in various wartime issues of the London Times the 
# acronym BDST for British Double Summer Time.  Look for the published 
# time of sunrise and sunset in The Times, when BDST was in effect, and 
# if you find a zone reference it will say, "All times B.D.S.T." 
 
# From Joseph S. Myers (1999-09-02): 
# ... some military cables (WO 219/4100 - this is a copy from the 
# main SHAEF archives held in the US National Archives, SHAEF/5252/8/516) 
# agree that the usage is BDST (this appears in a message dated 17 Feb 1945). 
 
# From Joseph S. Myers (2000-10-03): 
# On 18th April 1941, Sir Stephen Tallents of the BBC wrote to Sir 
# Alexander Maxwell of the Home Office asking whether there was any 
# official designation; the reply of the 21st was that there wasn't 
# but he couldn't think of anything better than the "Double British 
# Summer Time" that the BBC had been using informally.

# http://student.cusu.cam.ac.uk/~jsm28/british-time/ho-19410421.png 
 
# From Sir Alexander Maxwell in the above-mentioned letter (1941-04-21): 
# [N]o official designation has as far as I know been adopted for the time 
# which is to be introduced in May.... 
# I cannot think of anything better than "Double British Summer Time" 
# which could not be said to run counter to any official description. 
 
# From Paul Eggert (2000-10-02): 
# Howse writes (p 157) `DBST' too, but `BDST' seems to have been common 
# and follows the more usual convention of putting the location name first, 
# so we use `BDST'. 
 
# Peter Ilieve (1998-04-19) described at length 
# the history of summer time legislation in the United Kingdom. 
# Since 1998 Joseph S. Myers has been updating 
# and extending this list, which can be found in 
# <a href="http://student.cusu.cam.ac.uk/~jsm28/british-time/"> 
# History of legal time in Britain 
# </a> 
 
# From Joseph S. Myers (1998-01-06): 
# 
# The legal time in the UK outside of summer time is definitely GMT, not UTC; 
# see Lord Tanlaw's speech 
# <a href="http://www.parliament.the-stationery-office.co.uk/pa/ld199697/ldhansrd/pdvn/lds97/text/70611-20.htm#70611-20_head0"> 
# (Lords Hansard 11 June 1997 columns 964 to 976) 
# </a>. 
 
# From Paul Eggert (2006-03-22): 
# 
# For lack of other data, follow Shanks & Pottenger for Eire in 1940-1948. 
# 
# Given Ilieve and Myers's data, the following claims by Shanks & Pottenger 
# are incorrect: 
#     * Wales did not switch from GMT to daylight saving time until 
#       1921 Apr 3, when they began to conform with the rest of Great Britain. 
# Actually, Wales was identical after 1880. 
#     * Eire had two transitions on 1916 Oct 1. 
# It actually just had one transition. 
#     * Northern Ireland used single daylight saving time throughout WW II. 
# Actually, it conformed to Britain. 
#     * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18. 
# Actually, that date saw the usual switch to summer time. 
# Standard time was not changed until 1968-10-27 (the clocks didn't change). 
# 
# Here is another incorrect claim by Shanks & Pottenger: 
#     * Jersey, Guernsey, and the Isle of Man did not switch from GMT 
#       to daylight saving time until 1921 Apr 3, when they began to 
#       conform with Great Britain. 
# S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise. 
# 
# The following claim by Shanks & Pottenger is possible though doubtful; 
# we'll ignore it for now. 
#     * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00. 
# 
# 
# Whitman says Dublin Mean Time was -0:25:21, which is more precise than 
# Shanks & Pottenger. 
# Perhaps this was Dunsink Observatory Time, as Dunsink Observatory 
# (8 km NW of Dublin's center) seemingly was to Dublin as Greenwich was 
# to London.  For example: 
# 
#   "Timeball on the ballast office is down.  Dunsink time." 
#   -- James Joyce, Ulysses 
 
# From Joseph S. Myers (2005-01-26): 
# Irish laws are available online at www.irishstatutebook.ie.  These include 
# various relating to legal time, for example:

# 
# (These are those I found, but there could be more.  In any case these 
# should allow various updates to the comments in the europe file to cover 
# the laws applicable in Ireland.) 
# 
# (Note that the time in the Republic of Ireland since 1968 has been defined 
# in terms of standard time being GMT+1 with a period of winter time when it 
# is GMT, rather than standard time being GMT with a period of summer time 
# being GMT+1.) 
 
# From Paul Eggert (1999-03-28): 
# Clive Feather (<news:859845706.26043.0@office.demon.net>, 1997-03-31) 
# reports that Folkestone (Cheriton) Shuttle Terminal uses Concession Time 
# (CT), equivalent to French civil time. 
# Julian Hill (<news:36118128.5A14@virgin.net>, 1998-09-30) reports that 
# trains between Dollands Moor (the freight facility next door) 
# and Frethun run in CT. 
# My admittedly uninformed guess is that the terminal has two authorities, 
# the French concession operators and the British civil authorities, 
# and that the time depends on who you're talking to. 
# If, say, the British police were called to the station for some reason, 
# I would expect the official police report to use GMT/BST and not CET/CEST. 
# This is a borderline case, but for now let's stick to GMT/BST. 
 
# From an anonymous contributor (1996-06-02): 
# The law governing time in Ireland is under Statutory Instrument SI 395/94, 
# which gives force to European Union 7th Council Directive # 94/21/EC. 
# Under this directive, the Minister for Justice in Ireland makes appropriate 
# regulations. I spoke this morning with the Secretary of the Department of 
# Justice (tel +353 1 678 9711) who confirmed to me that the correct name is 
# "Irish Summer Time", abbreviated to "IST".

# From Jesper Norgaard Welen (2008-07-13): 
# 
# I found what is probably a typo of 2:00 which should perhaps be 2:00s 
# in the C-Eur rule from tz database version 2008d (this part was 
# corrected in version 2008d). The circumstancial evidence is simply the 
# tz database itself, as seen below:

# It seems that Paris, Monaco, Rule France, Rule Belgium all agree on 
# 2:00 standard time, e.g. 3:00 local time.  However there are no 
# countries that use C-Eur rules in September 1945, so the only items

# Previous editions of this database used abbreviations like MET DST 
# for Central European Summer Time, but this didn't agree with common usage. 
 
# From Markus Kuhn (1996-07-12): 
# The official German names ... are 
# 
#       Mitteleuropaeische Zeit (MEZ)         = UTC+01:00 
#       Mitteleuropaeische Sommerzeit (MESZ)  = UTC+02:00 
# 
# as defined in the German Time Act (Gesetz ueber die Zeitbestimmung (ZeitG), 
# 1978-07-25, Bundesgesetzblatt, Jahrgang 1978, Teil I, S. 1110-1111).... 
# I wrote ... to the German Federal Physical-Technical Institution 
# 
#       Physikalisch-Technische Bundesanstalt (PTB) 
#       Laboratorium 4.41 "Zeiteinheit" 
#       Postfach 3345 
#       D-38023 Braunschweig 
#       phone: +49 531 592-0 
# 
# ... I received today an answer letter from Dr. Peter Hetzel, head of the PTB 
# department for time and frequency transmission.  He explained that the 
# PTB translates MEZ and MESZ into English as 
# 
#       Central European Time (CET)         = UTC+01:00 
#       Central European Summer Time (CEST) = UTC+02:00

# From Paul Eggert (2006-03-22): Shanks & Pottenger give 1918-06-16 and 
# 1945-11-18, but the Austrian Federal Office of Metrology and 
# Surveying (BEV) gives 1918-09-16 and for Vienna gives the "alleged" 
# date of 1945-04-12 with no time.  For the 1980-04-06 transition 
# Shanks & Pottenger give 02:00, the BEV 00:00.  Go with the BEV, 
# and guess 02:00 for 1945-04-12.

# Denmark, Faroe Islands, and Greenland 
 
# From Jesper Norgaard Welen (2005-04-26): 
# http://www.hum.aau.dk/~poe/tid/tine/DanskTid.htm says that the law 
# [introducing standard time] was in effect from 1894-01-01.... 
# The page http://www.retsinfo.dk/_GETDOCI_/ACCN/A18930008330-REGL 
# confirms this, and states that the law was put forth 1893-03-29. 
# 
# The EU treaty with effect from 1973: 
# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19722110030-REGL 
# 
# This provoked a new law from 1974 to make possible summer time changes 
# in subsequenet decrees with the law 
# http://www.retsinfo.dk/_GETDOCI_/ACCN/A19740022330-REGL 
# 
# It seems however that no decree was set forward until 1980.  I have 
# not found any decree, but in another related law, the effecting DST 
# changes are stated explicitly to be from 1980-04-06 at 02:00 to 
# 1980-09-28 at 02:00.  If this is true, this differs slightly from 
# the EU rule in that DST runs to 02:00, not 03:00.  We don't know 
# when Denmark began using the EU rule correctly, but we have only 
# confirmation of the 1980-time, so I presume it was correct in 1981: 
# The law is about the management of the extra hour, concerning 
# working hours reported and effect on obligatory-rest rules (which 
# was suspended on that night): 
# http://www.retsinfo.dk/_GETDOCI_/ACCN/C19801120554-REGL 
 
# From Jesper Norgaard Welen (2005-06-11): 
# The Herning Folkeblad (1980-09-26) reported that the night between 
# Saturday and Sunday the clock is set back from three to two. 
 
# From Paul Eggert (2005-06-11): 
# Hence the "02:00" of the 1980 law refers to standard time, not 
# wall-clock time, and so the EU rules were in effect in 1980.

# From Paul Eggert (2004-10-31): 
# During World War II, Germany maintained secret manned weather stations in 
# East Greenland and Franz Josef Land, but we don't know their time zones. 
# My source for this is Wilhelm Dege's book mentioned under Svalbard. 
# 
# From Paul Eggert (2006-03-22): 
# Greenland joined the EU as part of Denmark, obtained home rule on 1979-05-01, 
# and left the EU on 1985-02-01.  It therefore should have been using EU 
# rules at least through 1984.  Shanks & Pottenger say Scoresbysund and Godthab 
# used C-Eur rules after 1980, but IATA SSIM (1991/1996) says they use EU 
# rules since at least 1991.  Assume EU rules since 1980. 
 
# From Gwillin Law (2001-06-06), citing 
# <http://www.statkart.no/efs/efshefter/2001/efs5-2001.pdf> (2001-03-15), 
# and with translations corrected by Steffen Thorsen: 
# 
# Greenland has four local times, and the relation to UTC 
# is according to the following time line: 
# 
# The military zone near Thule  UTC-4 
# Standard Greenland time       UTC-3 
# Scoresbysund                  UTC-1 
# Danmarkshavn                  UTC 
# 
# In the military area near Thule and in Danmarkshavn DST will not be 
# introduced. 
 
# From Rives McDow (2001-11-01): 
# 
# I correspond regularly with the Dansk Polarcenter, and wrote them at 
# the time to clarify the situation in Thule.  Unfortunately, I have 
# not heard back from them regarding my recent letter.  [But I have 
# info from earlier correspondence.] 
# 
# According to the center, a very small local time zone around Thule 
# Air Base keeps the time according to UTC-4, implementing daylight 
# savings using North America rules, changing the time at 02:00 local time.... 
# 
# The east coast of Greenland north of the community of Scoresbysund 
# uses UTC in the same way as in Iceland, year round, with no dst. 
# There are just a few stations on this coast, including the 
# Danmarkshavn ICAO weather station mentioned in your September 29th 
# email.  The other stations are two sledge patrol stations in 
# Mestersvig and Daneborg, the air force base at Station Nord, and the 
# DPC research station at Zackenberg. 
# 
# Scoresbysund and two small villages nearby keep time UTC-1 and use 
# the same daylight savings time period as in West Greenland (Godthab). 
# 
# The rest of Greenland, including Godthab (this area, although it 
# includes central Greenland, is known as west Greenland), keeps time 
# UTC-3, with daylight savings methods according to European rules. 
# 
# It is common procedure to use UTC 0 in the wilderness of East and 
# North Greenland, because it is mainly Icelandic aircraft operators 
# maintaining traffic in these areas.  However, the official status of 
# this area is that it sticks with Godthab time.  This area might be 
# considered a dual time zone in some respects because of this. 
 
# From Rives McDow (2001-11-19): 
# I heard back from someone stationed at Thule; the time change took place 
# there at 2:00 AM. 
 
# From Paul Eggert (2006-03-22): 
# From 1997 on the CIA map shows Danmarkshavn on GMT; 
# the 1995 map as like Godthab. 
# For lack of better info, assume they were like Godthab before 1996. 
# startkart.no says Thule does not observe DST, but this is clearly an error, 
# so go with Shanks & Pottenger for Thule transitions until this year. 
# For 2007 on assume Thule will stay in sync with US DST rules.

# Estonia 
# From Peter Ilieve (1994-10-15): 
# A relative in Tallinn confirms the accuracy of the data for 1989 onwards 
# [through 1994] and gives the legal authority for it, 
# a regulation of the Government of Estonia, No. 111 of 1989.... 
# 
# From Peter Ilieve (1996-10-28): 
# [IATA SSIM (1992/1996) claims that the Baltic republics switch at 01:00s, 
# but a relative confirms that Estonia still switches at 02:00s, writing:] 
# ``I do not [know] exactly but there are some little different 
# (confusing) rules for International Air and Railway Transport Schedules 
# conversion in Sunday connected with end of summer time in Estonia.... 
# A discussion is running about the summer time efficiency and effect on 
# human physiology.  It seems that Estonia maybe will not change to 
# summer time next spring.'' 
 
# From Peter Ilieve (1998-11-04), heavily edited: 
# <a href="http://trip.rk.ee/cgi-bin/thw?${BASE}=akt&${OOHTML}=rtd&TA=1998&TO=1&AN=1390"> 
# The 1998-09-22 Estonian time law 
# </a> 
# refers to the Eighth Directive and cites the association agreement between 
# the EU and Estonia, ratified by the Estonian law (RT II 1995, 22--27, 120). 
# 
# I also asked [my relative] whether they use any standard abbreviation 
# for their standard and summer times. He says no, they use "suveaeg" 
# (summer time) and "talveaeg" (winter time). 
 
# From <a href="http://www.baltictimes.com/">The Baltic Times</a> (1999-09-09) 
# via Steffen Thorsen: 
# This year will mark the last time Estonia shifts to summer time, 
# a council of the ruling coalition announced Sept. 6.... 
# But what this could mean for Estonia's chances of joining the European 
# Union are still unclear.  In 1994, the EU declared summer time compulsory 
# for all member states until 2001.  Brussels has yet to decide what to do 
# after that. 
 
# From Mart Oruaas (2000-01-29): 
# Regulation no. 301 (1999-10-12) obsoletes previous regulation 
# no. 206 (1998-09-22) and thus sticks Estonia to +02:00 GMT for all 
# the year round.  The regulation is effective 1999-11-01. 
 
# From Toomas Soome (2002-02-21): 
# The Estonian government has changed once again timezone politics. 
# Now we are using again EU rules.

# From Urmet Jaanes (2002-03-28):

# Iceland 
# 
# From Adam David (1993-11-06): 
# The name of the timezone in Iceland for system / mail / news purposes is GMT. 
# 
# (1993-12-05): 
# This material is paraphrased from the 1988 edition of the University of 
# Iceland Almanak. 
# 
# From January 1st, 1908 the whole of Iceland was standardised at 1 hour 
# behind GMT. Previously, local mean solar time was used in different parts 
# of Iceland, the almanak had been based on Reykjavik mean solar time which 
# was 1 hour and 28 minutes behind GMT. 
# 
# "first day of winter" referred to [below] means the first day of the 26 weeks 
# of winter, according to the old icelandic calendar that dates back to the 
# time the norsemen first settled Iceland.  The first day of winter is always 
# Saturday, but is not dependent on the Julian or Gregorian calendars. 
# 
# (1993-12-10): 
# I have a reference from the Oxford Icelandic-English dictionary for the 
# beginning of winter, which ties it to the ecclesiastical calendar (and thus 
# to the julian/gregorian calendar) over the period in question. 
#       the winter begins on the Saturday next before St. Luke's day 
#       (old style), or on St. Luke's day, if a Saturday. 
# St. Luke's day ought to be traceable from ecclesiastical sources. "old style" 
# might be a reference to the Julian calendar as opposed to Gregorian, or it 
# might mean something else (???). 
# 
# From Paul Eggert (2006-03-22): 
# The Iceland Almanak, Shanks & Pottenger, and Whitman disagree on many points. 
# We go with the Almanak, except for one claim from Shanks & Pottenger, namely 
# that Reykavik was 21W57 from 1837 to 1908, local mean time before that.

# Italy 
# 
# From Paul Eggert (2001-03-06): 
# Sicily and Sardinia each had their own time zones from 1866 to 1893, 
# called Palermo Time (+00:53:28) and Cagliari Time (+00:36:32). 
# During World War II, German-controlled Italy used German time. 
# But these events all occurred before the 1970 cutoff, 
# so record only the time in Rome. 
# 
# From Paul Eggert (2006-03-22):

# Latvia 
 
# From Liene Kanepe (1998-09-17): 
 
# I asked about this matter Scientific Secretary of the Institute of Astronomy 
# of The University of Latvia Dr. paed Mr. Ilgonis Vilks. I also searched the 
# correct data in juridical acts and I found some juridical documents about 
# changes in the counting of time in Latvia from 1981.... 
# 
# Act No.35 of the Council of Ministers of Latvian SSR of 1981-01-22 ... 
# according to the Act No.925 of the Council of Ministers of USSR of 1980-10-24 
# ...: all year round the time of 2nd time zone + 1 hour, in addition turning 
# the hands of the clock 1 hour forward on 1 April at 00:00 (GMT 31 March 21:00) 
# and 1 hour backward on the 1 October at 00:00 (GMT 30 September 20:00). 
# 
# Act No.592 of the Council of Ministers of Latvian SSR of 1984-09-24 ... 
# according to the Act No.967 of the Council of Ministers of USSR of 1984-09-13 
# ...: all year round the time of 2nd time zone + 1 hour, in addition turning 
# the hands of the clock 1 hour forward on the last Sunday of March at 02:00 
# (GMT 23:00 on the previous day) and 1 hour backward on the last Sunday of 
# September at 03:00 (GMT 23:00 on the previous day). 
# 
# Act No.81 of the Council of Ministers of Latvian SSR of 1989-03-22 ... 
# according to the Act No.227 of the Council of Ministers of USSR of 1989-03-14 
# ...: since the last Sunday of March 1989 in Lithuanian SSR, Latvian SSR, 
# Estonian SSR and Kaliningrad region of Russian Federation all year round the 
# time of 2nd time zone (Moscow time minus one hour). On the territory of Latvia 
# transition to summer time is performed on the last Sunday of March at 02:00 
# (GMT 00:00), turning the hands of the clock 1 hour forward.  The end of 
# daylight saving time is performed on the last Sunday of September at 03:00 
# (GMT 00:00), turning the hands of the clock 1 hour backward. Exception is 
# 1989-03-26, when we must not turn the hands of the clock.... 
# 
# The Regulations of the Cabinet of Ministers of the Republic of Latvia of 
# 1997-01-21 on transition to Summer time ... established the same order of 
# daylight savings time settings as in the States of the European Union. 
 
# From Andrei Ivanov (2000-03-06): 
# This year Latvia will not switch to Daylight Savings Time (as specified in 
# <a href="http://www.lv-laiks.lv/wwwraksti/2000/071072/vd4.htm"> 
# The Regulations of the Cabinet of Ministers of the Rep. of Latvia of

# <a href="http://www.rferl.org/newsline/2001/01/3-CEE/cee-030101.html"> 
# From RFE/RL Newsline (2001-01-03), noted after a heads-up by Rives McDow: 
# </a> 
# The Latvian government on 2 January decided that the country will 
# institute daylight-saving time this spring, LETA reported. 
# Last February the three Baltic states decided not to turn back their 
# clocks one hour in the spring.... 
# Minister of Economy Aigars Kalvitis noted that Latvia had too few 
# daylight hours and thus decided to comply with a draft European 
# Commission directive that provides for instituting daylight-saving 
# time in EU countries between 2002 and 2006. The Latvian government 
# urged Lithuania and Estonia to adopt a similar time policy, but it 
# appears that they will not do so....

# From Paul Eggert (1996-11-22): 
# IATA SSIM (1992/1996) says Lithuania uses W-Eur rules, but since it is 
# known to be wrong about Estonia and Latvia, assume it's wrong here too. 
 
# From Marius Gedminas (1998-08-07): 
# I would like to inform that in this year Lithuanian time zone 
# (Europe/Vilnius) was changed. 
 
# From <a href="http://www.elta.lt/">ELTA</a> No. 972 (2582) (1999-09-29), 
# via Steffen Thorsen: 
# Lithuania has shifted back to the second time zone (GMT plus two hours) 
# to be valid here starting from October 31, 
# as decided by the national government on Wednesday.... 
# The Lithuanian government also announced plans to consider a 
# motion to give up shifting to summer time in spring, as it was 
# already done by Estonia. 
 
# From the <a href="http://www.tourism.lt/informa/ff.htm"> 
# Fact File, Lithuanian State Department of Tourism 
# </a> (2000-03-27): Local time is GMT+2 hours ..., no daylight saving. 
 
# From a user via Klaus Marten (2003-02-07): 
# As a candidate for membership of the European Union, Lithuania will 
# observe Summer Time in 2003, changing its clocks at the times laid 
# down in EU Directive 2000/84 of 19.I.01 (i.e. at the same times as its 
# neighbour Latvia). The text of the Lithuanian government Order of 
# 7.XI.02 to this effect can be found at

# Moldova 
 
# From Paul Eggert (2006-03-22): 
# A previous version of this database followed Shanks & Pottenger, who write 
# that Tiraspol switched to Moscow time on 1992-01-19 at 02:00. 
# However, this is most likely an error, as Moldova declared independence 
# on 1991-08-27 (the 1992-01-19 date is that of a Russian decree). 
# In early 1992 there was large-scale interethnic violence in the area 
# and it's possible that some Russophones continued to observe Moscow time. 
# But [two people] separately reported via 
# Jesper Norgaard that as of 2001-01-24 Tiraspol was like Chisinau. 
# The Tiraspol entry has therefore been removed for now.

# Netherlands 
 
# Howse writes that the Netherlands' railways used GMT between 1892 and 1940, 
# but for other purposes the Netherlands used Amsterdam mean time. 
 
# However, Robert H. van Gent writes (2001-04-01): 
# Howse's statement is only correct up to 1909. From 1909-05-01 (00:00:00 
# Amsterdam mean time) onwards, the whole of the Netherlands (including 
# the Dutch railways) was required by law to observe Amsterdam mean time 
# (19 minutes 32.13 seconds ahead of GMT). This had already been the 
# common practice (except for the railways) for many decades but it was 
# not until 1909 when the Dutch government finally defined this by law. 
# On 1937-07-01 this was changed to 20 minutes (exactly) ahead of GMT and 
# was generally known as Dutch Time ("Nederlandse Tijd"). 
# 
# (2001-04-08): 
# 1892-05-01 was the date when the Dutch railways were by law required to 
# observe GMT while the remainder of the Netherlands adhered to the common 
# practice of following Amsterdam mean time. 
# 
# (2001-04-09): 
# In 1835 the authorities of the province of North Holland requested the 
# municipal authorities of the towns and cities in the province to observe 
# Amsterdam mean time but I do not know in how many cases this request was 
# actually followed. 
# 
# From 1852 onwards the Dutch telegraph offices were by law required to 
# observe Amsterdam mean time. As the time signals from the observatory of 
# Leiden were also distributed by the telegraph system, I assume that most 
# places linked up with the telegraph (and railway) system automatically 
# adopted Amsterdam mean time. 
# 
# Although the early Dutch railway companies initially observed a variety 
# of times, most of them had adopted Amsterdam mean time by 1858 but it 
# was not until 1866 when they were all required by law to observe 
# Amsterdam mean time. 
 
# The data before 1945 are taken from

# Svalbard & Jan Mayen 
 
# From Steffen Thorsen (2001-05-01): 
# Although I could not find it explicitly, it seems that Jan Mayen and 
# Svalbard have been using the same time as Norway at least since the 
# time they were declared as parts of Norway.  Svalbard was declared 
# as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan 
# Mayen by law of 1930-02-27 no 2, section 2. (From 
# http://www.lovdata.no/all/nl-19250717-011.html and 
# http://www.lovdata.no/all/nl-19300227-002.html).  The law/regulation 
# for normal/standard time in Norway is from 1894-06-29 no 1 (came 
# into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a 
# part of this law since 1925/1930. (From 
# http://www.lovdata.no/all/nl-18940629-001.html ) I have not been 
# able to find if Jan Mayen used a different time zone (e.g. -0100) 
# before 1930. Jan Mayen has only been "inhabitated" since 1921 by 
# Norwegian meteorologists and maybe used the same time as Norway ever 
# since 1921.  Svalbard (Arctic/Longyearbyen) has been inhabited since 
# before 1895, and therefore probably changed the local time somewhere 
# between 1895 and 1925 (inclusive). 
 
# From Paul Eggert (2001-05-01): 
# 
# Actually, Jan Mayen was never occupied by Germany during World War II, 
# so it must have diverged from Oslo time during the war, as Oslo was 
# keeping Berlin time. 
# 
# <http://home.no.net/janmayen/history.htm> says that the meteorologists 
# burned down their station in 1940 and left the island, but returned in 
# 1941 with a small Norwegian garrison and continued operations despite 
# frequent air ttacks from Germans.  In 1943 the Americans established a 
# radiolocating station on the island, called "Atlantic City".  Possibly 
# the UTC offset changed during the war, but I think it unlikely that 
# Jan Mayen used German daylight-saving rules. 
# 
# Svalbard is more complicated, as it was raided in August 1941 by an 
# Allied party that evacuated the civilian population to England (says 
# <http://www.bartleby.com/65/sv/Svalbard.html>).  The Svalbard FAQ 
# <http://www.svalbard.com/SvalbardFAQ.html> says that the Germans were 
# expelled on 1942-05-14.  However, small parties of Germans did return, 
# and according to Wilhelm Dege's book "War North of 80" (1954) 
# <http://www.ucalgary.ca/UofC/departments/UP/1-55238/1-55238-110-2.html> 
# the German armed forces at the Svalbard weather station code-named 
# Haudegen did not surrender to the Allies until September 1945. 
# 
# All these events predate our cutoff date of 1970.  Unless we can 
# come up with more definitive info about the timekeeping during the 
# war years it's probably best just do do the following for now:

# Portugal 
# 
# From Rui Pedro Salgueiro (1992-11-12): 
# Portugal has recently (September, 27) changed timezone 
# (from WET to MET or CET) to harmonize with EEC. 
# 
# Martin Bruckmann (1996-02-29) reports via Peter Ilieve 
# that Portugal is reverting to 0:00 by not moving its clocks this spring. 
# The new Prime Minister was fed up with getting up in the dark in the winter. 
# 
# From Paul Eggert (1996-11-12): 
# IATA SSIM (1991-09) reports several 1991-09 and 1992-09 transitions 
# at 02:00u, not 01:00u.  Assume that these are typos. 
# IATA SSIM (1991/1992) reports that the Azores were at -1:00. 
# IATA SSIM (1993-02) says +0:00; later issues (through 1996-09) say -1:00. 
# Guess that the Azores changed to EU rules in 1992 (since that's when Portugal 
# harmonized with the EU), and that they stayed +0:00 that winter.

# Russia 
 
# From Paul Eggert (2006-03-22): 
# Except for Moscow after 1919-07-01, I invented the time zone abbreviations. 
# Moscow time zone abbreviations after 1919-07-01, and Moscow rules after 1991, 
# are from Andrey A. Chernov.  The rest is from Shanks & Pottenger, 
# except we follow Chernov's report that 1992 DST transitions were Sat 
# 23:00, not Sun 02:00s. 
# 
# From Stanislaw A. Kuzikowski (1994-06-29): 
# But now it is some months since Novosibirsk is 3 hours ahead of Moscow! 
# I do not know why they have decided to make this change; 
# as far as I remember it was done exactly during winter->summer switching 
# so we (Novosibirsk) simply did not switch. 
# 
# From Andrey A. Chernov (1996-10-04): 
# `MSK' and `MSD' were born and used initially on Moscow computers with 
# UNIX-like OSes by several developer groups (e.g. Demos group, Kiae group).... 
# The next step was the UUCP network, the Relcom predecessor 
# (used mainly for mail), and MSK/MSD was actively used there. 
# 
# From Chris Carrier (1996-10-30): 
# According to a friend of mine who rode the Trans-Siberian Railroad from 
# Moscow to Irkutsk in 1995, public air and rail transport in Russia ... 
# still follows Moscow time, no matter where in Russia it is located. 
# 
# For Grozny, Chechnya, we have the following story from 
# John Daniszewski, "Scavengers in the Rubble", Los Angeles Times (2001-02-07): 
# News--often false--is spread by word of mouth.  A rumor that it was 
# time to move the clocks back put this whole city out of sync with 
# the rest of Russia for two weeks--even soldiers stationed here began 
# enforcing curfew at the wrong time. 
# 
# From Gwillim Law (2001-06-05): 
# There's considerable evidence that Sakhalin Island used to be in 
# UTC+11, and has changed to UTC+10, in this decade.  I start with the 
# SSIM, which listed Yuzhno-Sakhalinsk in zone RU10 along with Magadan 
# until February 1997, and then in RU9 with Khabarovsk and Vladivostok 
# since September 1997....  Although the Kuril Islands are 
# administratively part of Sakhalin oblast', they appear to have 
# remained on UTC+11 along with Magadan.

# From Ivan Nilsson (2001-04-13), superseding Shanks & Pottenger: 
# 
# The law "Svensk forfattningssamling 1878, no 14" about standard time in 1879: 
# From the beginning of 1879 (that is 01-01 00:00) the time for all 
# places in the country is "the mean solar time for the meridian at 
# three degrees, or twelve minutes of time, to the west of the 
# meridian of the Observatory of Stockholm".  The law is dated 1878-05-31. 
# 
# The observatory at that time had the meridian 18 degrees 03' 30" 
# eastern longitude = 01:12:14 in time.  Less 12 minutes gives the 
# national standard time as 01:00:14 ahead of GMT.... 
# 
# About the beginning of CET in Sweden. The lawtext ("Svensk 
# forfattningssamling 1899, no 44") states, that "from the beginning 
# of 1900... ... the same as the mean solar time for the meridian at 
# the distance of one hour of time from the meridian of the English 
# observatory at Greenwich, or at 12 minutes 14 seconds to the west 
# from the meridian of the Observatory of Stockholm". The law is dated 
# 1899-06-16.  In short: At 1900-01-01 00:00:00 the new standard time 
# in Sweden is 01:00:00 ahead of GMT. 
# 
# 1916: The lawtext ("Svensk forfattningssamling 1916, no 124") states 
# that "1916-05-15 is considered to begin one hour earlier". It is 
# pretty obvious that at 05-14 23:00 the clocks are set to 05-15 00:00.... 
# Further the law says, that "1916-09-30 is considered to end one hour later". 
# 
# The laws regulating [DST] are available on the site of the Swedish 
# Parliament beginning with 1985 - the laws regulating 1980/1984 are 
# not available on the site (to my knowledge they are only available 
# in Swedish): <http://www.riksdagen.se/english/work/sfst.asp> (type 
# "sommartid" without the quotes in the field "Fritext" and then click 
# the Sok-button). 
# 
# (2001-05-13): 
# 
# I have now found a newspaper stating that at 1916-10-01 01:00 
# summertime the church-clocks etc were set back one hour to show 
# 1916-10-01 00:00 standard time.  The article also reports that some 
# people thought the switch to standard time would take place already 
# at 1916-10-01 00:00 summer time, but they had to wait for another 
# hour before the event took place.

# From Alois Treindl (2008-12-17): 
# I have researched the DST usage in Switzerland during the 1940ies. 
# 
# As I wrote in an earlier message, I suspected the current tzdata values 
# to be wrong. This is now verified. 
# 
# I have found copies of the original ruling by the Swiss Federal 
# government, in 'Eidgen[o]ssische Gesetzessammlung 1941 and 1942' (Swiss 
# federal law collection)... 
# 
# DST began on Monday 5 May 1941, 1:00 am by shifting the clocks to 2:00 am 
# DST ended on Monday 6 Oct 1941, 2:00 am by shifting the clocks to 1:00 am. 
# 
# DST began on Monday, 4 May 1942 at 01:00 am 
# DST ended on Monday, 5 Oct 1942 at 02:00 am 
# 
# There was no DST in 1940, I have checked the law collection carefully. 
# It is also indicated by the fact that the 1942 entry in the law 
# collection points back to 1941 as a reference, but no reference to any 
# other years are made. 
# 
# Newspaper articles I have read in the archives on 6 May 1941 reported 
# about the introduction of DST (Sommerzeit in German) during the previous 
# night as an absolute novelty, because this was the first time that such 
# a thing had happened in Switzerland. 
# 
# I have also checked 1916, because one book source (Gabriel, Traite de 
# l'heure dans le monde) claims that Switzerland had DST in 1916. This is 
# false, no official document could be found. Probably Gabriel got misled 
# by references to Germany, which introduced DST in 1916 for the first time. 
# 
# The tzdata rules for Switzerland must be changed to: 
# Rule  Swiss   1941    1942    -       May     Mon>=1  1:00    1:00    S 
# Rule  Swiss   1941    1942    -       Oct     Mon>=1  2:00    0       - 
# 
# The 1940 rules must be deleted. 
# 
# One further detail for Switzerland, which is probably out of scope for 
# most users of tzdata: 
# The zone file

# From Sue Williams (2008-08-20): 
# This article says that around the end of March 2011, Turkey wants to 
# adjust the clocks forward by 1/2 hour and stay that way permanently. 
# The article indicates that this is a change in timezone offset in addition 
# to stopping observance of DST. 
# This proposal has not yet been approved.

# According to Bernard Sieloff's source, Poland is in the MET time zone but

# Bernard Sieloff's source claims Romania switches on the same day, but at

# 
# ...the European time rules are...standardized since 1981, when 
# most European coun[tr]ies started DST.  Before that year, only 
# a few countries (UK, France, Italy) had DST, each according 
# to own national rules.  In 1981, however, DST started on 
# 'Apr firstSun', and not on 'Mar lastSun' as in the following 
# years... 
# But also since 1981 there are some more national exceptions 
# than listed in 'europe': Switzerland, for example, joined DST 
# one year later, Denmark ended DST on 'Oct 1' instead of 'Sep 
# lastSun' in 1981---I don't know how they handle now. 
# 
# Finally, DST ist always from 'Apr 1' to 'Oct 1' in the 
# Soviet Union (as far as I know).

# ... 
# 
# The information from Tom Hofmann is (as far as I know) not entirely correct. 
# After a request from chongo at amdahl I tried to retrieve all information 
# about DST in Europe.  I was able to find all from about 1969. 
# 
# ...standardization on DST in Europe started in about 1977 with switches on 
# first Sunday in April and last Sunday in September... 
# In 1981 UK joined Europe insofar that 
# the starting day for both shifted to last Sunday in March.  And from 1982 
# the whole of Europe used DST, with switch dates April 1 and October 1 in 
# the Sov[i]et Union.  In 1985 the SU reverted to standard Europe[a]n switch 
# dates... 
# 
# It should also be remembered that time-zones are not constants; e.g. 
# Portugal switched in 1976 from MET (or CET) to WET with DST... 
# Note also that though there were rules for switch dates not 
# all countries abided to these dates, and many individual deviations 
# occurred, though not since 1982 I believe.  Another note: it is always 
# assumed that DST is 1 hour ahead of normal time, this need not be the 
# case; at least in the Netherlands there have been times when DST was 2 hours 
# in advance of normal time.
