Below find a first pass at changes to "zone.tabb" and "asia" to handle Uyghur variants of time in China. The basic approach is to have zones with Han-based names for the rules used by Han, and zones with Uyghur-based names for the rules used by Uyghur. --ado ------- zone.tab ------- *** /tmp/geta21843 Sat Nov 21 10:34:46 2009 --- /tmp/getb21843 Sat Nov 21 10:34:46 2009 *************** *** 1,5 **** # <pre> ! # @(#)zone.tab 8.29 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. # --- 1,5 ---- # <pre> ! # @(#)zone.tab 8.30 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. # *************** *** 148,155 **** CN +3114+12128 Asia/Shanghai east China - Beijing, Guangdong, Shanghai, etc. CN +4545+12641 Asia/Harbin Heilongjiang (except Mohe), Jilin CN +2934+10635 Asia/Chongqing central China - Sichuan, Yunnan, Guangxi, Shaanxi, Guizhou, etc. !

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.
