The government of the Xinjiang 4872386db68SMarcel Telka# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as 4882386db68SMarcel Telka# local governments such as the Ürümqi city government use both times in 4892386db68SMarcel Telka# publications, referring to what is popularly called Xinjiang time as 4902386db68SMarcel Telka# "Ürümqi time." When Uyghurs make an appointment in the Uyghur language 4912386db68SMarcel Telka# they almost invariably use Xinjiang time. 4922386db68SMarcel Telka# 4932386db68SMarcel Telka# (Their ethnic Han compatriots would typically have no clue of its 4942386db68SMarcel Telka# widespread use, however, because so extremely few of them are fluent in 4952386db68SMarcel Telka# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.) 4962386db68SMarcel Telka# 4972386db68SMarcel Telka# (...As with the rest of China there was a brief interval ending in 1990 4982386db68SMarcel Telka# or 1991 when summer time was in use. The confusion was severe, with 4992386db68SMarcel Telka# the province not having dual times but four times in use at the same 5002386db68SMarcel Telka# time. Some areas remained on standard Xinjiang time or Beijing time and 5012386db68SMarcel Telka# others moving their clocks ahead.) 5022386db68SMarcel Telka 5032386db68SMarcel Telka# From Luther Ma (2009-11-19): 5042386db68SMarcel Telka# With the risk of being redundant to previous answers these are the most common 5052386db68SMarcel Telka# English "transliterations" (w/o using non-English symbols): 5062386db68SMarcel Telka# 5072386db68SMarcel Telka# 1.

It seems that Uyghurs in Ürümqi has been using Xinjiang since at least the 5132386db68SMarcel Telka# 1960's. I know of one Han, now over 50, who grew up in the surrounding 5142386db68SMarcel Telka# countryside and used Xinjiang time as a child. 5152386db68SMarcel Telka# 5162386db68SMarcel Telka# 6. Likewise for Kashgar and the rest of south Xinjiang I don't know of any 5172386db68SMarcel Telka# start date for Xinjiang time. 5182386db68SMarcel Telka# 5192386db68SMarcel Telka# Without having access to local historical records, nor the ability to legally 5202386db68SMarcel Telka# publish them, I would go with October 1, 1949, when Xinjiang became the Uyghur 5212386db68SMarcel Telka# Autonomous Region under the PRC. (Before that Uyghurs, of course, would also 5222386db68SMarcel Telka# not be using Beijing time, but some local time.) 5232386db68SMarcel Telka 5242386db68SMarcel Telka# From David Cochrane (2014-03-26): 5252386db68SMarcel Telka# Just a confirmation that Ürümqi time was implemented in Ürümqi on 1 Feb 1986: 526f34ea95cSYuri Pankov# https://content.time.com/time/magazine/article/0,9171,960684,00.html 5272386db68SMarcel Telka 5282386db68SMarcel Telka# From Luther Ma (2014-04-22): 5292386db68SMarcel Telka# I have interviewed numerous people of various nationalities and from 5302386db68SMarcel Telka# different localities in Xinjiang and can confirm the information in Guo's 5312386db68SMarcel Telka# report regarding Xinjiang, as well as the Time article reference by David 5322386db68SMarcel Telka# Cochrane. Whether officially recognized or not (and both are officially 5332386db68SMarcel Telka# recognized), two separate times have been in use in Xinjiang since at least 5342386db68SMarcel Telka# the Cultural Revolution: Xinjiang Time (XJT), aka Ürümqi Time or local time; 5352386db68SMarcel Telka# and Beijing Time. There is no confusion in Xinjiang as to which name refers 5362386db68SMarcel Telka# to which time. Both are widely used in the province, although in some 5372386db68SMarcel Telka# population groups might be use one to the exclusion of the other. The only 5382386db68SMarcel Telka# problem is that computers and smart phones list Ürümqi (or Kashgar) as 5392386db68SMarcel Telka# having the same time as Beijing. 5402386db68SMarcel Telka 5412386db68SMarcel Telka# From Paul Eggert (2014-06-30): 5422386db68SMarcel Telka# In the early days of the PRC, Tibet was given its own time zone (UT +06) 5432386db68SMarcel Telka# but this was withdrawn in 1959 and never reinstated; see Tubten Khétsun, 5442386db68SMarcel Telka# Memories of life in Lhasa under Chinese Rule, Columbia U Press, ISBN 5452386db68SMarcel Telka# 978-0231142861 (2008), translator's introduction by Matthew Akester, p x. 5462386db68SMarcel Telka# As this is before our 1970 cutoff, Tibet doesn't need a separate zone. 5472386db68SMarcel Telka# 5482386db68SMarcel Telka# Xinjiang Time is well-documented as being officially recognized.

Approximate this lost history by a transition from LMT to 5572386db68SMarcel Telka# UT +06 at the start of 1928, the year of accession of the warlord Jin Shuren, 5582386db68SMarcel Telka# which happens to be the date given by Shanks & Pottenger (no doubt as a 5592386db68SMarcel Telka# guess) as the transition from LMT. Ignore the usage of +08 before 5602386db68SMarcel Telka# 1986-02-01 under the theory that the transition date to +08 is unknown and 5612386db68SMarcel Telka# that the sort of users who prefer Asia/Urumqi now typically ignored the 5622386db68SMarcel Telka# +08 mandate back then. 5632386db68SMarcel Telka 5642386db68SMarcel Telka# Zone NAME GMTOFF RULES FORMAT [UNTIL] 5652386db68SMarcel Telka# Beijing time, used throughout China; represented by Shanghai. 5662386db68SMarcel TelkaZone Asia/Shanghai 8:05:43 - LMT 1901 567*4d6441a8SAndy Fiddaman 8:00 Shang C%sT 1949 May 28 5682386db68SMarcel Telka 8:00 PRC C%sT 5692386db68SMarcel Telka# Xinjiang time, used by many in western China; represented by Ürümqi / Ürümchi 5702386db68SMarcel Telka# / Wulumuqi.

From 1993-1998, the change to 14582386db68SMarcel Telka# daylight savings time was on a Friday morning from midnight IST to 14592386db68SMarcel Telka# 1 a.m IDT; up until 1998, the change back to standard time was on a 14602386db68SMarcel Telka# Saturday night from midnight daylight savings time to 11 p.m. standard 14612386db68SMarcel Telka# time. 1996 is an exception to this rule where the change back to standard 14622386db68SMarcel Telka# time took place on Sunday night instead of Saturday night to avoid 14632386db68SMarcel Telka# conflicts with the Jewish New Year. In 1999, the change to 14642386db68SMarcel Telka# daylight savings time was still on a Friday morning but from 14652386db68SMarcel Telka# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time 14662386db68SMarcel Telka# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for 14672386db68SMarcel Telka# 1999 only. In the year 2000, the change to daylight savings time was 14682386db68SMarcel Telka# similar to 1999, but although the change back will be on a Friday, it 14692386db68SMarcel Telka# will take place from 1 a.m. IDT to midnight IST.

It was never formally annexed to Egypt, 25962386db68SMarcel Telka# though. 25972386db68SMarcel Telka# 25982386db68SMarcel Telka# The rest of Palestine was under Jordanian rule at that time, formally 25992386db68SMarcel Telka# annexed in 1950 as the West Bank (and the word "Trans" was dropped from 26002386db68SMarcel Telka# the country's previous name of "the Hashemite Kingdom of the 26012386db68SMarcel Telka# Trans-Jordan"). So the rules for Jordan for that time apply. Major 26022386db68SMarcel Telka# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and 26032386db68SMarcel Telka# East Jerusalem. 26042386db68SMarcel Telka# 26052386db68SMarcel Telka# Both areas were occupied by Israel in June 1967, but not annexed (except 26062386db68SMarcel Telka# for East Jerusalem).

Richard P Hunt, in "Islam city yielding to 29872386db68SMarcel Telka# modern times", New York Times (1961-04-09), p 20, wrote that only airlines 29882386db68SMarcel Telka# observed standard time, and that people in Jeddah mostly observed quasi-solar 29892386db68SMarcel Telka# time, doing so by setting their watches at sunrise to 6 o'clock (or to 12 29902386db68SMarcel Telka# o'clock for "Arab" time). 29912386db68SMarcel Telka# 2992*4d6441a8SAndy Fiddaman# Timekeeping differed depending on who you were and which part of Saudi 2993*4d6441a8SAndy Fiddaman# Arabia you were in. In 1969, Elias Antar wrote that although a common 2994*4d6441a8SAndy Fiddaman# practice had been to set one's watch to 12:00 (i.e., midnight) at sunset - 2995*4d6441a8SAndy Fiddaman# which meant that the time on one side of a mountain could differ greatly from 2996*4d6441a8SAndy Fiddaman# the time on the other side - many foreigners set their watches to 6pm 2997*4d6441a8SAndy Fiddaman# instead, while airlines instead used UTC +03 (except in Dhahran, where they 2998*4d6441a8SAndy Fiddaman# used UTC +04), Aramco used UTC +03 with DST, and the Trans-Arabian Pipe Line 2999*4d6441a8SAndy Fiddaman# Company used Aramco time in eastern Saudi Arabia and airline time in western. 3000*4d6441a8SAndy Fiddaman# (The American Military Aid Advisory Group used plain UTC.) Antar writes, 3001*4d6441a8SAndy Fiddaman# "A man named Higgins, so the story goes, used to run a local power 3002*4d6441a8SAndy Fiddaman# station. One day, the whole thing became too much for Higgins and he 3003*4d6441a8SAndy Fiddaman# assembled his staff and laid down the law. 'I've had enough of this,' he 3004*4d6441a8SAndy Fiddaman# shrieked. 'It is now 12 o'clock Higgins Time, and from now on this station is 3005*4d6441a8SAndy Fiddaman# going to run on Higgins Time.' And so, until last year, it did." See: 3006*4d6441a8SAndy Fiddaman# Antar E. Dinner at When?

The 1946 foreign air news digest of the U.S. Civil Aeronautics 30132386db68SMarcel Telka# Board (OCLC 42299995) reported that the "...
