The government of the Xinjiang 434# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as 435# local governments such as the Urumqi city government use both times in 436# publications, referring to what is popularly called Xinjiang time as 437# "Urumqi time." When Uyghurs make an appointment in the Uyghur language 438# they almost invariably use Xinjiang time. 439# 440# (Their ethnic Han compatriots would typically have no clue of its 441# widespread use, however, because so extremely few of them are fluent in 442# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.) 443# 444# (...As with the rest of China there was a brief interval ending in 1990 445# or 1991 when summer time was in use. The confusion was severe, with 446# the province not having dual times but four times in use at the same 447# time.
