However, Guo also says that the 349# evidence is dubious, as the relevant institute of astronomy had not 350# been taken over by the PRC yet. It's plausible that apparent solar 351# time was announced but never implemented, and that people continued 352# to use UT+8. As the Shanghai radio station (and I presume the 353# observatory) was still under control of French missionaries, it 354# could well have ignored any such mandate. 355# 356# (2) 357# Guo Qing-sheng (Shaanxi Astronomical Observatory, CAS, Xi'an 710600, China) 358# A Study on the Standard Time Changes for the Past 100 Years in China 359# [undated and unknown publication location] 360# It says several things: 361# * The Qing dynasty used local apparent solar time throughout China. 362# * The Republic of China instituted Beijing mean solar time effective 363# the official calendar book of 1914. 364# * The French Concession in Shanghai set up signal stations in 365# French docks in the 1890s, controlled by Xujiahui (Zikawei) 366# Observatory and set to local mean time. 367# * "From the end of the 19th century" it changed to UT+8. 368# * Chinese Customs (by then reduced to a tool of foreign powers) 369# eventually standardized on this time for all ports, and it 370# became used by railways as well. 371# * In 1918 the Central Observatory proposed dividing China into 372# five time zones (see below for details). This caught on 373# at first only in coastal areas observing UT+8. 374# * During WWII all of China was in theory was at UT+7. In practice 375# this was ignored in the west, and I presume was ignored in 376# Japanese-occupied territory. 377# * Japanese-occupied Manchuria was at UT+9, i.e., Japan time. 378# * The five-zone plan was resurrected after WWII and officially put into 379# place (with some modifications) in March 1948. It's not clear 380# how well it was observed in areas under Nationalist control. 381# * The People's Liberation Army used UT+8 during the civil war. 382# 383# An AP article "Shanghai Internat'l Area Little Changed" in the 384# Lewiston (ME) Daily Sun (1939-05-29), p 17, said "Even the time is 385# different - the occupied districts going by Tokyo time, an hour 386# ahead of that prevailing in the rest of Shanghai." Guess that the 387# Xujiahui Observatory was under French control and stuck with UT+8. 388# 389# In earlier versions of this file, China had many separate Zone entries, but 390# this was based on what were apparently incorrect data in Shanks & Pottenger. 391# This has now been simplified to the two entries Asia/Shanghai and 392# Asia/Urumqi, with the others being links for backward compatibility. 393# Proposed in 1918 and theoretically in effect until 1949 (although in practice 394# mainly observed in coastal areas), the five zones were: 395# 396# Changbai Time ("Long-white Time", Long-white = Heilongjiang area) UT+8.5 397# Asia/Harbin (currently a link to Asia/Shanghai) 398# Heilongjiang (except Mohe county), Jilin 399# 400# Zhongyuan Time ("Central plain Time") UT+8 401# Asia/Shanghai 402# most of China 403# This currently represents most other zones as well, 404# as apparently these regions have been the same since 1970. 405# Milne gives 8:05:43.2 for Xujiahui Observatory time; round to nearest. 406# Guo says Shanghai switched to UT+8 "from the end of the 19th century". 407# 408# Long-shu Time (probably due to Long and Shu being two names of that area) UT+7 409# Asia/Chongqing (currently a link to Asia/Shanghai) 410# Guangxi, Guizhou, Hainan, Ningxia, Sichuan, Shaanxi, and Yunnan; 411# most of Gansu; west Inner Mongolia; west Qinghai; and the Guangdong 412# counties Deqing, Enping, Kaiping, Luoding, Taishan, Xinxing, 413# Yangchun, Yangjiang, Yu'nan, and Yunfu. 414# 415# Xin-zang Time ("Xinjiang-Tibet Time") UT+6 416# Asia/Urumqi 417# This currently represents Kunlun Time as well, 418# as apparently the two regions have been the same since 1970. 419# The Gansu counties Aksay, Anxi, Dunhuang, Subei; west Qinghai; 420# the Guangdong counties Xuwen, Haikang, Suixi, Lianjiang, 421# Zhanjiang, Wuchuan, Huazhou, Gaozhou, Maoming, Dianbai, and Xinyi; 422# east Tibet, including Lhasa, Chamdo, Shigaise, Jimsar, Shawan and Hutubi; 423# east Xinjiang, including Ürümqi, Turpan, Karamay, Korla, Minfeng, Jinghe, 424# Wusu, Qiemo, Xinyan, Wulanwusu, Jinghe, Yumin, Tacheng, Tuoli, Emin, 425# Shihezi, Changji, Yanqi, Heshuo, Tuokexun, Tulufan, Shanshan, Hami, 426# Fukang, Kuitun, Kumukuli, Miquan, Qitai, and Turfan. 427# 428# Kunlun Time UT+5.5 429# Asia/Kashgar (currently a link to Asia/Urumqi) 430# West Tibet, including Pulan, Aheqi, Shufu, Shule; 431# West Xinjiang, including Aksu, Atushi, Yining, Hetian, Cele, Luopu, Nileke, 432# Zhaosu, Tekesi, Gongliu, Chabuchaer, Huocheng, Bole, Pishan, Suiding, 433# and Yarkand. 434 435# From Luther Ma (2009-10-17): 436# Almost all (>99.9%) ethnic Chinese (properly ethnic Han) living in 437# Xinjiang use Chinese Standard Time. Some are aware of Xinjiang time, 438# but have no need of it. All planes, trains, and schools function on 439# what is called "Beijing time."

The government of the Xinjiang 445# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as 446# local governments such as the Ürümqi city government use both times in 447# publications, referring to what is popularly called Xinjiang time as 448# "Ürümqi time." When Uyghurs make an appointment in the Uyghur language 449# they almost invariably use Xinjiang time. 450# 451# (Their ethnic Han compatriots would typically have no clue of its 452# widespread use, however, because so extremely few of them are fluent in 453# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.) 454# 455# (...As with the rest of China there was a brief interval ending in 1990 456# or 1991 when summer time was in use. The confusion was severe, with 457# the province not having dual times but four times in use at the same 458# time. Some areas remained on standard Xinjiang time or Beijing time and 459# others moving their clocks ahead.) 460 461# From Luther Ma (2009-11-19): 462# With the risk of being redundant to previous answers these are the most common 463# English "transliterations" (w/o using non-English symbols): 464# 465# 1. Wulumuqi... 466# 2. Kashi... 467# 3. Urumqi... 468# 4. Kashgar... 469# ... 470# 5. It seems that Uyghurs in Ürümqi has been using Xinjiang since at least the 471# 1960's. I know of one Han, now over 50, who grew up in the surrounding 472# countryside and used Xinjiang time as a child. 473# 474# 6. Likewise for Kashgar and the rest of south Xinjiang I don't know of any 475# start date for Xinjiang time. 476# 477# Without having access to local historical records, nor the ability to legally 478# publish them, I would go with October 1, 1949, when Xinjiang became the Uyghur 479# Autonomous Region under the PRC. (Before that Uyghurs, of course, would also 480# not be using Beijing time, but some local time.) 481 482# From David Cochrane (2014-03-26): 483# Just a confirmation that Ürümqi time was implemented in Ürümqi on 1 Feb 1986: 484# http://content.time.com/time/magazine/article/0,9171,960684,00.html 485 486# From Luther Ma (2014-04-22): 487# I have interviewed numerous people of various nationalities and from 488# different localities in Xinjiang and can confirm the information in Guo's 489# report regarding Xinjiang, as well as the Time article reference by David 490# Cochrane. Whether officially recognized or not (and both are officially 491# recognized), two separate times have been in use in Xinjiang since at least 492# the Cultural Revolution: Xinjiang Time (XJT), aka Ürümqi Time or local time; 493# and Beijing Time. There is no confusion in Xinjiang as to which name refers 494# to which time. Both are widely used in the province, although in some 495# population groups might be use one to the exclusion of the other. The only 496# problem is that computers and smart phones list Ürümqi (or Kashgar) as 497# having the same time as Beijing. 498 499# From Paul Eggert (2014-06-30): 500# In the early days of the PRC, Tibet was given its own time zone (UT+6) but 501# this was withdrawn in 1959 and never reinstated; see Tubten Khétsun, 502# Memories of life in Lhasa under Chinese Rule, Columbia U Press, ISBN 503# 978-0231142861 (2008), translator's introduction by Matthew Akester, p x. 504# As this is before our 1970 cutoff, Tibet doesn't need a separate zone. 505# 506# Xinjiang Time is well-documented as being officially recognized. E.g., see 507# "The Working-Calendar for The Xinjiang Uygur Autonomous Region Government" 508# <http://www.sinkiang.gov.cn/service/ourworking/> (2014-04-22). 509# Unfortunately, we have no good records of time in Xinjiang before 1986. 510# During the 20th century parts of Xinjiang were ruled by the Qing dynasty, 511# the Republic of China, various warlords, the First and Second East Turkestan 512# Republics, the Soviet Union, the Kuomintang, and the People's Republic of 513# China, and tracking down all these organizations' timekeeping rules would be 514# quite a trick.

It was never formally annexed to Egypt, 2315# though. 2316# 2317# The rest of Palestine was under Jordanian rule at that time, formally 2318# annexed in 1950 as the West Bank (and the word "Trans" was dropped from 2319# the country's previous name of "the Hashemite Kingdom of the 2320# Trans-Jordan"). So the rules for Jordan for that time apply. Major 2321# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and 2322# East Jerusalem. 2323# 2324# Both areas were occupied by Israel in June 1967, but not annexed (except 2325# for East Jerusalem).
