# Armenia

# From Paul Eggert (2006-03-22):

# Shanks & Pottenger have Yerevan switching to 3:00 (with Russian DST)

# in spring 1991, then to 4:00 with no DST in fall 1995, then

# readopting Russian DST in 1997.  Go with Shanks & Pottenger, even

# when they disagree with others.  Edgar Der-Danieliantz

# reported (1996-05-04) that Yerevan probably wouldn't use DST

# in 1996, though it did use DST in 1995.  IATA SSIM (1991/1998) reports that

# but started switching at 3:00s in 1998.

# From Guy Harris:

# From Bob Devine (1988-01-28):

# No they don't.  See TIME mag, 1986-02-17 p.52.  Even though

# China is across 4 physical time zones, before Feb 1, 1986 only the

# Peking (Beijing) time zone was recognized.  Since that date, China

# has two of 'em - Peking's and Ürümqi (named after the capital of

# the Xinjiang Uyghur Autonomous Region).  I don't know about DST for it.

#

# . . .I just deleted the DST table and this editor makes it too

# DST start/end dates for Peking's time zone (info from AP):

#

#     1986 May 4 - Sept 14

#     1987 mid-April - ??

# From U. S. Naval Observatory (1989-01-19):

# CHINA               8 H  AHEAD OF UTC  ALL OF CHINA, INCL TAIWAN

# Shanks & Pottenger have China switching to a single time zone in 1980, but

# this doesn't seem to be correct.  They also write that China observed summer

# DST from 1986 through 1991, which seems to match the above commentary, so

#

# From Jesper Nørgaard Welen (2006-07-14):

# I have investigated the timezones around 1970 on the

# http://www.astro.com/atlas site [with provinces and county

# boundaries summarized below]....  A few other exceptions were two

# counties on the Sichuan side of the Xizang-Sichuan border,

# counties Dege and Baiyu which lies on the Sichuan side and are

# therefore supposed to be GMT+7, Xizang region being GMT+6, but Dege

# county is GMT+8 according to astro.com while Baiyu county is GMT+6

# (could be true), for the moment I am assuming that those two

# counties are mistakes in the astro.com data.

# From Paul Eggert (2014-06-30):

# Alois Treindl kindly sent me translations of the following two sources:

#

# (1)

# Guo Qingsheng (National Time-Service Center, CAS, Xi'an 710600, China)

# Beijing Time at the Beginning of the PRC

# China Historical Materials of Science and Technology

# (Zhongguo ke ji shi liao, 中国科技史料), Vol. 24, No. 1 (2003)

# It gives evidence that at the beginning of the PRC, Beijing time was

# officially apparent solar time!  However, Guo also says that the

# evidence is dubious, as the relevant institute of astronomy had not

# been taken over by the PRC yet.  It's plausible that apparent solar

# time was announced but never implemented, and that people continued

# to use UT+8.  As the Shanghai radio station (and I presume the

# observatory) was still under control of French missionaries, it

# could well have ignored any such mandate.

#

# (2)

# Guo Qing-sheng (Shaanxi Astronomical Observatory, CAS, Xi'an 710600, China)

# A Study on the Standard Time Changes for the Past 100 Years in China

# [undated and unknown publication location]

# It says several things:

#   * The Qing dynasty used local apparent solar time throughout China.

#   * The Republic of China instituted Beijing mean solar time effective

#     the official calendar book of 1914.

#   * The French Concession in Shanghai set up signal stations in

#     French docks in the 1890s, controlled by Xujiahui (Zikawei)

#     Observatory and set to local mean time.

#   * "From the end of the 19th century" it changed to UT+8.

#   * Chinese Customs (by then reduced to a tool of foreign powers)

#     eventually standardized on this time for all ports, and it

#     became used by railways as well.

#   * In 1918 the Central Observatory proposed dividing China into

#     five time zones (see below for details).  This caught on

#     at first only in coastal areas observing UT+8.

#   * During WWII all of China was in theory was at UT+7.  In practice

#     this was ignored in the west, and I presume was ignored in

#     Japanese-occupied territory.

#   * Japanese-occupied Manchuria was at UT+9, i.e., Japan time.

#   * The five-zone plan was resurrected after WWII and officially put into

#     place (with some modifications) in March 1948.  It's not clear

#     how well it was observed in areas under Nationalist control.

#   * The People's Liberation Army used UT+8 during the civil war.

#

# An AP article "Shanghai Internat'l Area Little Changed" in the

# Lewiston (ME) Daily Sun (1939-05-29), p 17, said "Even the time is

# different - the occupied districts going by Tokyo time, an hour

# ahead of that prevailing in the rest of Shanghai."  Guess that the

# Xujiahui Observatory was under French control and stuck with UT+8.

#

# In earlier versions of this file, China had many separate Zone entries, but

# this was based on what were apparently incorrect data in Shanks & Pottenger.

# This has now been simplified to the two entries Asia/Shanghai and

# Asia/Urumqi, with the others being links for backward compatibility.

# Proposed in 1918 and theoretically in effect until 1949 (although in practice

# mainly observed in coastal areas), the five zones were:

#

# Changbai Time ("Long-white Time", Long-white = Heilongjiang area) UT+8.5

# Asia/Harbin (currently a link to Asia/Shanghai)

# Heilongjiang (except Mohe county), Jilin

#

# Zhongyuan Time ("Central plain Time") UT+8

# Asia/Shanghai

# most of China

# This currently represents most other zones as well,

# as apparently these regions have been the same since 1970.

# Milne gives 8:05:43.2 for Xujiahui Observatory time; round to nearest.

# Guo says Shanghai switched to UT+8 "from the end of the 19th century".

#

# Long-shu Time (probably due to Long and Shu being two names of that area) UT+7

# Asia/Chongqing (currently a link to Asia/Shanghai)

# Guangxi, Guizhou, Hainan, Ningxia, Sichuan, Shaanxi, and Yunnan;

# most of Gansu; west Inner Mongolia; west Qinghai; and the Guangdong

# counties Deqing, Enping, Kaiping, Luoding, Taishan, Xinxing,

# Yangchun, Yangjiang, Yu'nan, and Yunfu.

#

# Xin-zang Time ("Xinjiang-Tibet Time") UT+6

# Asia/Urumqi

# This currently represents Kunlun Time as well,

# as apparently the two regions have been the same since 1970.

# The Gansu counties Aksay, Anxi, Dunhuang, Subei; west Qinghai;

# the Guangdong counties  Xuwen, Haikang, Suixi, Lianjiang,

# Zhanjiang, Wuchuan, Huazhou, Gaozhou, Maoming, Dianbai, and Xinyi;

# east Tibet, including Lhasa, Chamdo, Shigaise, Jimsar, Shawan and Hutubi;

# east Xinjiang, including Ürümqi, Turpan, Karamay, Korla, Minfeng, Jinghe,

# Wusu, Qiemo, Xinyan, Wulanwusu, Jinghe, Yumin, Tacheng, Tuoli, Emin,

# Shihezi, Changji, Yanqi, Heshuo, Tuokexun, Tulufan, Shanshan, Hami,

# Fukang, Kuitun, Kumukuli, Miquan, Qitai, and Turfan.

#

# Kunlun Time UT+5.5

# Asia/Kashgar (currently a link to Asia/Urumqi)

# West Tibet, including Pulan, Aheqi, Shufu, Shule;

# West Xinjiang, including Aksu, Atushi, Yining, Hetian, Cele, Luopu, Nileke,

# Zhaosu, Tekesi, Gongliu, Chabuchaer, Huocheng, Bole, Pishan, Suiding,

# and Yarkand.

# 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 Ürümqi city government use both times in

# publications, referring to what is popularly called Xinjiang time as

# "Ürümqi 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.)

# 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 Ürümqi 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 David Cochrane (2014-03-26):

# Just a confirmation that Ürümqi time was implemented in Ürümqi on 1 Feb 1986:

# http://content.time.com/time/magazine/article/0,9171,960684,00.html

# From Luther Ma (2014-04-22):

# I have interviewed numerous people of various nationalities and from

# different localities in Xinjiang and can confirm the information in Guo's

# report regarding Xinjiang, as well as the Time article reference by David

# Cochrane.  Whether officially recognized or not (and both are officially

# recognized), two separate times have been in use in Xinjiang since at least

# the Cultural Revolution: Xinjiang Time (XJT), aka Ürümqi Time or local time;

# and Beijing Time.  There is no confusion in Xinjiang as to which name refers

# to which time. Both are widely used in the province, although in some

# population groups might be use one to the exclusion of the other.  The only

# problem is that computers and smart phones list Ürümqi (or Kashgar) as

# having the same time as Beijing.

# From Paul Eggert (2014-06-30):

# In the early days of the PRC, Tibet was given its own time zone (UT+6) but

# this was withdrawn in 1959 and never reinstated; see Tubten Khétsun,

# Memories of life in Lhasa under Chinese Rule, Columbia U Press, ISBN

# 978-0231142861 (2008), translator's introduction by Matthew Akester, p x.

# As this is before our 1970 cutoff, Tibet doesn't need a separate zone.

#

# Xinjiang Time is well-documented as being officially recognized.  E.g., see

# "The Working-Calendar for The Xinjiang Uygur Autonomous Region Government"
