In practice +# this was ignored in the west, and I presume was ignored in +# Japanese-occupied territory. +# * Japanese-occupied Manchuria was at UT+9, i.e., Japan time. +# * The five-zone plan was resurrected after WWII and officially put into +# place (with some modifications) in March 1948. It's not clear +# how well it was observed in areas under Nationalist control. +# * The People's Liberation Army used UT+8 during the civil war. +# +# An AP article "Shanghai Internat'l Area Little Changed" in the +# Lewiston (ME) Daily Sun (1939-05-29), p 17, said "Even the time is +# different - the occupied districts going by Tokyo time, an hour +# ahead of that prevailing in the rest of Shanghai."

The government of the Xinjiang +# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as +# local governments such as the Ürümqi city government use both times in +# publications, referring to what is popularly called Xinjiang time as +# "Ürümqi 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.) + +# From Luther Ma (2009-11-19): +# With the risk of being redundant to previous answers these are the most common +# English "transliterations" (w/o using non-English symbols): +# +# 1. Wulumuqi... +# 2. Kashi... +# 3. Urumqi... +# 4. Kashgar... +# ... +# 5. It seems that Uyghurs in Ürümqi 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. (Before that Uyghurs, of course, would also +# not be using Beijing time, but some local time.) + +# From David Cochrane (2014-03-26): +# Just a confirmation that Ürümqi time was implemented in Ürümqi on 1 Feb 1986: +# http://content.time.com/time/magazine/article/0,9171,960684,00.html + +# From Luther Ma (2014-04-22): +# I have interviewed numerous people of various nationalities and from +# different localities in Xinjiang and can confirm the information in Guo's +# report regarding Xinjiang, as well as the Time article reference by David +# Cochrane. Whether officially recognized or not (and both are officially +# recognized), two separate times have been in use in Xinjiang since at least +# the Cultural Revolution: Xinjiang Time (XJT), aka Ürümqi Time or local time; +# and Beijing Time. There is no confusion in Xinjiang as to which name refers +# to which time. Both are widely used in the province, although in some +# population groups might be use one to the exclusion of the other. The only +# problem is that computers and smart phones list Ürümqi (or Kashgar) as +# having the same time as Beijing. + +# From Paul Eggert (2014-06-30): +# In the early days of the PRC, Tibet was given its own time zone (UT +06) +# but this was withdrawn in 1959 and never reinstated; see Tubten Khétsun, +# Memories of life in Lhasa under Chinese Rule, Columbia U Press, ISBN +# 978-0231142861 (2008), translator's introduction by Matthew Akester, p x. +# As this is before our 1970 cutoff, Tibet doesn't need a separate zone. +# +# Xinjiang Time is well-documented as being officially recognized. E.g., see +# "The Working-Calendar for The Xinjiang Uygur Autonomous Region Government" +# (2014-04-22). +# Unfortunately, we have no good records of time in Xinjiang before 1986. +# During the 20th century parts of Xinjiang were ruled by the Qing dynasty, +# the Republic of China, various warlords, the First and Second East Turkestan +# Republics, the Soviet Union, the Kuomintang, and the People's Republic of +# China, and tracking down all these organizations' timekeeping rules would be +# quite a trick.
