  Calendrical issues are a bit out of scope for a time zone database,
  but they indicate the sort of problems that we would run into if we
  extended the time zone database further into the past.  An excellent
! resource in this area is Edward M. Reingold and Nachum Dershowitz,

  # West Xinjiang, including Aksu, Atushi, Yining, Hetian, Cele, Luopu, Nileke,
  # Zhaosu, Tekesi, Gongliu, Chabuchaer, Huocheng, Bole, Pishan, Suiding,
  # and Yarkand.
+ 
+ # 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

+ # (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. As of yesterday, 18:30, Urumqi City Fire officers and men
+ # > have worked continuously for 22 hours...
+ 
+ # 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 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. (Before that Uyghurs, of course, would also
+ # not be using Beijing time, but some local time.)
