c621d92010-01-19Henrik Grubbström (Grubba)  # From Luther Ma (2009-10-17): # Almost all (>99.9%) ethnic Chinese (properly ethnic Han) living in # Xinjiang use Chinese Standard Time. Some are aware of Xinjiang time, # but have no need of it. All planes, trains, and schools function on # what is called "Beijing time." When Han make an appointment in Chinese # they implicitly use Beijing time. # # On the other hand, ethnic Uyghurs, who make up about half the # population of Xinjiang, typically use "Xinjiang time" which is two # hours behind Beijing time, or UTC +0600. The government of the Xinjiang # Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as # local governments such as the Urumqi city government use both times in # publications, referring to what is popularly called Xinjiang time as # "Urumqi time." When Uyghurs make an appointment in the Uyghur language # they almost invariably use Xinjiang time. # # (Their ethnic Han compatriots would typically have no clue of its # widespread use, however, because so extremely few of them are fluent in # Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.) # # (...As with the rest of China there was a brief interval ending in 1990 # or 1991 when summer time was in use. The confusion was severe, with # the province not having dual times but four times in use at the same # time. Some areas remained on standard Xinjiang time or Beijing time and # others moving their clocks ahead.) # # ...an example of an official website using of Urumqi time. # # The first few lines of the Google translation of # <a href="http://www.fjysgl.gov.cn/show.aspx?id=2379&cid=39"> # http://www.fjysgl.gov.cn/show.aspx?id=2379&cid=39 # </a> # (retrieved 2009-10-13) # > Urumqi fire seven people are missing the alleged losses of at least # > 500 million yuan # > # > (Reporter Dong Liu) the day before 20:20 or so (Urumqi Time 18:20), # > Urumqi City Department of International Plaza Luther Qiantang River # > burst fire.

Wulumuqi... # 2. Kashi... # 3. Urumqi... # 4. Kashgar... # ... # 5. It seems that Uyghurs in Urumqi has been using Xinjiang since at least the # 1960's. I know of one Han, now over 50, who grew up in the surrounding # countryside and used Xinjiang time as a child. # # 6. Likewise for Kashgar and the rest of south Xinjiang I don't know of any # start date for Xinjiang time. # # Without having access to local historical records, nor the ability to legally # publish them, I would go with October 1, 1949, when Xinjiang became the Uyghur # Autonomous Region under the PRC.

84701a2007-02-01Henrik Grubbström (Grubba) # # From Roozbeh Pournader (2005-04-05): # The text of the Iranian law, in effect since 1925, clearly mentions # that the true solar year is the measure, and there is no arithmetic # leap year calculation involved. There has never been any serious # plan to change that law.... # # From Paul Eggert (2006-03-22): # Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter. # I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates, # stopping after 2037 when 32-bit time_t's overflow. # That cal-persia used Birashk's approximation, which disagrees with the solar # calendar predictions for the year 2025, so I corrected those dates by hand. # # From Oscar van Vlijmen (2005-03-30), writing about future # discrepancies between cal-persia and the Iranian calendar: # For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for # the vernal equinox and that gets so close to 12:00 some local # Iranian time that the definition of the correct location needs to be # known exactly, amongst other factors. 2157 is even closer: # 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give # no interpretation problem whatsoever. By the way, another instant # in the near future where there will be a discrepancy between # arithmetical and astronomical Iranian calendars will be in 2058: # vernal equinox on 2058-03-20 09:03:05.9 UT. The Java version of # Reingold's/Dershowitz' calculator gives correctly the Gregorian date # 2058-03-21 for 1 Farvardin 1437 (astronomical). # # From Steffen Thorsen (2006-03-22): # Several of my users have reported that Iran will not observe DST anymore: # http://www.irna.ir/en/news/view/line-17/0603193812164948.htm

The dates of implementation I am # unsure of, but most probably it was similar to Russia, except for the time # of implementation may have been different.... # Some maps in the past have indicated that there was an additional time # zone in the eastern part of Mongolia, including the provinces of Dornod, # Suhbaatar, and possibly Khentij. # From Paul Eggert (1999-12-15): # Naming and spelling is tricky in Mongolia. # We'll use Hovd (also spelled Chovd and Khovd) to represent the west zone; # the capital of the Hovd province is sometimes called Hovd, sometimes Dund-Us, # and sometimes Jirgalanta (with variant spellings), but the name Hovd # is good enough for our purposes.

84701a2007-02-01Henrik Grubbström (Grubba) # From Amos Shapir (1998-02-15):
c0dbee2000-08-01Mirar (Pontus Hagland) # # From 1917 until 1948-05-15, all of Palestine, including the parts now # known as the Gaza Strip and the West Bank, was under British rule. # Therefore the rules given for Israel for that period, apply there too... # # The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05 # (except a short occupation by Israel from 1956-11 till 1957-03, but no # time zone was affected then). It was never formally annexed to Egypt, # though. # # The rest of Palestine was under Jordanian rule at that time, formally # annexed in 1950 as the West Bank (and the word "Trans" was dropped from # the country's previous name of "the Hashemite Kingdom of the # Trans-Jordan"). So the rules for Jordan for that time apply. Major # towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and # East Jerusalem. # # Both areas were occupied by Israel in June 1967, but not annexed (except # for East Jerusalem). They were on Israel time since then; there might # have been a Military Governor's order about time zones, but I'm not aware # of any (such orders may have been issued semi-annually whenever summer # time was in effect, but maybe the legal aspect of time was just neglected). # # The Palestinian Authority was established in 1993, and got hold of most # towns in the West Bank and Gaza by 1995. I know that in order to # demonstrate...independence, they have been switching to # summer time and back on a different schedule than Israel's, but I don't # know when this was started, or what algorithm is used (most likely the # Jordanian one). # # To summarize, the table should probably look something like that: # # Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996- # ------------+-----------+-----------+-----------+----------- # Israel | Zion | Zion | Zion | Zion # West bank | Zion | Jordan | Zion | Jordan # Gaza | Zion | Egypt | Zion | Jordan # # I guess more info may be available from the PA's web page (if/when they # have one).

84701a2007-02-01Henrik Grubbström (Grubba) # From Paul Eggert (2005-11-22): # Starting 2004 transitions are from Steffen Thorsen's web site timeanddate.com. # From Steffen Thorsen (2005-11-23): # A user from Gaza reported that Gaza made the change early because of # the Ramadan. Next year Ramadan will be even earlier, so I think # there is a good chance next year's end date will be around two weeks # earlier--the same goes for Jordan. # From Steffen Thorsen (2006-08-17): # I was informed by a user in Bethlehem that in Bethlehem it started the # same day as Israel, and after checking with other users in the area, I # was informed that they started DST one day after Israel. I was not # able to find any authoritative sources at the time, nor details if # Gaza changed as well, but presumed Gaza to follow the same rules as # the West Bank. # From Steffen Thorsen (2006-09-26): # according to the Palestine News Network (2006-09-19): # http://english.pnn.ps/index.php?option=com_content&task=view&id=596&Itemid=5 # > The Council of Ministers announced that this year its winter schedule # > will begin early, as of midnight Thursday.

ca883b2008-04-03Henrik Grubbström (Grubba) # From Jesper Norgaard Welen (2007-09-18): # According to Steffen Thorsen's web site the Gaza Strip and the rest of the # Palestinian territories left DST early on 13.th. of September at 2:00. # From Paul Eggert (2007-09-20): # My understanding is that Gaza and the West Bank disagree even over when # the weekend is (Thursday+Friday versus Friday+Saturday), so I'd be a bit # surprised if they agreed about DST. But for now, assume they agree. # For lack of better information, predict that future changes will be # the 2nd Thursday of September at 02:00.
