The government of the Xinjiang 426# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as 427# local governments such as the Urumqi city government use both times in 428# publications, referring to what is popularly called Xinjiang time as 429# "Urumqi time." When Uyghurs make an appointment in the Uyghur language 430# they almost invariably use Xinjiang time. 431# 432# (Their ethnic Han compatriots would typically have no clue of its 433# widespread use, however, because so extremely few of them are fluent in 434# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.) 435# 436# (...As with the rest of China there was a brief interval ending in 1990 437# or 1991 when summer time was in use. The confusion was severe, with 438# the province not having dual times but four times in use at the same 439# time.
