# Zones that go back beyond the scope of the tz database 
 
# This file is in the public domain. 
 
# This file is by no means authoritative; if you think you know 
# better, go ahead and edit it (and please send any changes to 
# tz@iana.org for general use in the future).  For more, please see 
# the file CONTRIBUTING in the tz distribution. 
 
 
# From Paul Eggert (2014-10-31): 
 
# This file contains data outside the normal scope of the tz database, 
# in that its zones do not differ from normal tz zones after 1970. 
# Links in this file point to zones in this file, superseding links in 
# the file 'backward'. 
 
# Although zones in this file may be of some use for analyzing 
# pre-1970 time stamps, they are less reliable, cover only a tiny 
# sliver of the pre-1970 era, and cannot feasibly be improved to cover 
# most of the era.  Because the zones are out of normal scope for the 
# database, less effort is put into maintaining this file.  Many of 
# the zones were formerly in other source files, but were removed or 
# replaced by links as their data entries were questionable and/or they 
# differed from other zones only in pre-1970 time stamps. 
 
# Unless otherwise specified, the source for data through 1990 is: 
# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition), 
# San Diego: ACS Publications, Inc. (2003). 
# Unfortunately this book contains many errors and cites no sources. 
 
# This file is not intended to be compiled standalone, as it 
# assumes rules from other files.  In the tz distribution, use 
# 'make PACKRATDATA=backzone zones' to compile and install this file. 
 
# Zones are sorted by zone name.  Each zone is preceded by the 
# name of the country that the zone is in, along with any other 
# commentary and rules associated with the entry. 
# 
# As explained in the zic man page, the zone columns are: 
# Zone  NAME            GMTOFF  RULES   FORMAT  [UNTIL] 
 
# Ethiopia 
# From Paul Eggert (2014-07-31): 
# Like the Swahili of Kenya and Tanzania, many Ethiopians keep a 
# 12-hour clock starting at our 06:00, so their "8 o'clock" is our 
# 02:00 or 14:00.  Keep this in mind when you ask the time in Amharic. 
# 
# Shanks & Pottenger write that Ethiopia had six narrowly-spaced time 
# zones between 1870 and 1890, that they merged to 38E50 (2:35:20) in 
# 1890, and that they switched to 3:00 on 1936-05-05.  Perhaps 38E50 
# was for Adis Dera.  Quite likely the Shanks data entries are wrong 
# anyway.

# Isle of Man

# From Lester Caine (2013-09-04): 
# The Isle of Man legislation is now on-line at 
# <https://www.legislation.gov.im>, starting with the original Statutory 
# Time Act in 1883 and including additional confirmation of some of 
# the dates of the 'Summer Time' orders originating at 
# Westminster.  There is a little uncertainty as to the starting date 
# of the first summer time in 1916 which may have been announced a 
# couple of days late.  There is still a substantial number of 
# documents to work through, but it is thought that every GB change 
# was also implemented on the island.
