# This data is by no means authoritative; if you think you know better,

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

#

# A good source for time zone historical data outside the U.S. is

# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),

# San Diego: ACS Publications, Inc. (2003).

#

# Gwillim Law writes that a good source

# for recent time zone data is the International Air Transport

# Association's Standard Schedules Information Manual (IATA SSIM),

# published semiannually.  Law sent in several helpful summaries

# of the IATA's data after 1990.

#

# Except where otherwise noted, Shanks & Pottenger is the source for

# entries through 1990, and IATA SSIM is the source for entries afterwards.

#

# Another source occasionally used is Edward W. Whitman, World Time Differences,

# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which

# I found in the UCLA library.

#

# A reliable and entertaining source about time zones is

# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).

# 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

# Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991,

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

# From Arthur David Olson (2011-06-15):

# While Russia abandoned DST in 2011, Armenia may choose to

# follow Russia's "old" rules.

# From Alexander Krivenyshev (2012-02-10):

# According to News Armenia, on Feb 9, 2012,

# http://newsarmenia.ru/society/20120209/42609695.html

#

# The Armenia National Assembly adopted final reading of Amendments to the

# China

# From Guy Harris:

# People's Republic of China.  Yes, they really have only one time zone.

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

# has two of 'em -- Peking's and Urumqi (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

# painful to suck in another copy..  So, here is what I have for

# 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

# CHINA               9 H  AHEAD OF UTC  APR 17 - SEP 10

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

# Shanks & Pottenger write that China (except for Hong Kong and Macau)

# has had a single time zone since 1980 May 1, observing summer DST

# from 1986 through 1991; this contradicts Devine's

# note about Time magazine, though apparently _something_ happened in 1986.

# Go with Shanks & Pottenger for now.  I made up names for the other

# pre-1980 time zones.

# From Anthony Fok (2001-12-20):

# BTW, I did some research on-line and found some info regarding these five

# historic timezones from some Taiwan websites.  And yes, there are official

# Chinese names for these locales (before 1949).

#

# From Jesper Norgaard 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 (2008-02-11):

# I just now checked Google News for western news sources that talk

# about China's single time zone, and couldn't find anything before 1986

# talking about China being in one time zone.  (That article was: Jim

# Mann, "A clumsy embrace for another western custom: China on daylight

# time--sort of", Los Angeles Times, 1986-05-05.  By the way, this

# article confirms the tz database's data claiming that China began

# observing daylight saving time in 1986.

#

# From Thomas S. Mullaney (2008-02-11):

# I think you're combining two subjects that need to treated

# separately: daylight savings (which, you're correct, wasn't

# implemented until the 1980s) and the unified time zone centered near

# Beijing (which was implemented in 1949). Briefly, there was also a

# "Lhasa Time" in Tibet and "Urumqi Time" in Xinjiang. The first was

# ceased, and the second eventually recognized (again, in the 1980s).

#

# From Paul Eggert (2008-06-30):

# There seems to be a good chance China switched to a single time zone in 1949

# rather than in 1980 as Shanks & Pottenger have it, but we don't have a

# reliable documentary source saying so yet, so for now we still go with

# Shanks & Pottenger.

# 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 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.  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.)

#

# ...an example of an official website using of Urumqi time.

# 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 Urumqi 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 Lee Yiu Chung (2009-10-24):

# I found there are some mistakes for the...DST rule for Hong

# Kong. [According] to the DST record from Hong Kong Observatory (actually,

# it is not [an] observatory, but the official meteorological agency of HK,

# and also serves as the official timing agency), there are some missing

# and incorrect rules. Although the exact switch over time is missing, I

# think 3:30 is correct. The official DST record for Hong Kong can be

# obtained from
