+# 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.

+# 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.)
+
+# From Arthur David Olson (2009-11-21)
+# Use English transliterations of Han names of cities for names of zones using Han approaches;
+# use English transliterations of Uyghur names of cities for names of zones using Uyghur approaches.
+# Since (reportedly) at least some Uyghur have observed Beijing DST rules,
+# use PRC rules for Uyghur zones.
