Shanks and Rique Pottenger, The International Atlas (6th edition), 14# San Diego: ACS Publications, Inc. (2003). 15# 16# Gwillim Law writes that a good source 17# for recent time zone data is the International Air Transport 18# Association's Standard Schedules Information Manual (IATA SSIM), 19# published semiannually. Law sent in several helpful summaries 20# of the IATA's data after 1990. 21# 22# Except where otherwise noted, Shanks & Pottenger is the source for 23# entries through 1990, and IATA SSIM is the source for entries afterwards. 24# 25# Another source occasionally used is Edward W. Whitman, World Time Differences, 26# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which 27# I found in the UCLA library. 28# 29# A reliable and entertaining source about time zones is 30# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997). 31# 32# I invented the abbreviations marked `*' in the following table; 33# the rest are from earlier versions of this file, or from other sources. 34# Corrections are welcome! 35# std dst 36# LMT Local Mean Time 37# 2:00 EET EEST Eastern European Time 38# 2:00 IST IDT Israel 39# 3:00 AST ADT Arabia* 40# 3:30 IRST IRDT Iran 41# 4:00 GST Gulf* 42# 5:30 IST India 43# 7:00 ICT Indochina* 44# 7:00 WIT west Indonesia 45# 8:00 CIT central Indonesia 46# 8:00 CST China 47# 9:00 CJT Central Japanese Time (1896/1937)* 48# 9:00 EIT east Indonesia 49# 9:00 JST JDT Japan 50# 9:00 KST KDT Korea 51# 9:30 CST (Australian) Central Standard Time 52# 53# See the `europe' file for Russia and Turkey in Asia. 54 55# From Guy Harris: 56# Incorporates data for Singapore from Robert Elz' asia 1.1, as well as 57# additional information from Tom Yap, Sun Microsystems Intercontinental 58# Technical Support (including a page from the Official Airline Guide - 59# Worldwide Edition).

Even though 238# China is across 4 physical time zones, before Feb 1, 1986 only the 239# Peking (Bejing) time zone was recognized.

And yes, there are official 274# Chinese names for these locales (before 1949). 275# 276# From Jesper Norgaard Welen (2006-07-14): 277# I have investigated the timezones around 1970 on the 278# http://www.astro.com/atlas site [with provinces and county 279# boundaries summarized below].... A few other exceptions were two 280# counties on the Sichuan side of the Xizang-Sichuan border, 281# counties Dege and Baiyu which lies on the Sichuan side and are 282# therefore supposed to be GMT+7, Xizang region being GMT+6, but Dege 283# county is GMT+8 according to astro.com while Baiyu county is GMT+6 284# (could be true), for the moment I am assuming that those two 285# counties are mistakes in the astro.com data. 286 287# From Paul Eggert (2008-02-11): 288# I just now checked Google News for western news sources that talk 289# about China's single time zone, and couldn't find anything before 1986 290# talking about China being in one time zone. (That article was: Jim 291# Mann, "A clumsy embrace for another western custom: China on daylight 292# time--sort of", Los Angeles Times, 1986-05-05. By the way, this 293# article confirms the tz database's data claiming that China began 294# observing daylight saving time in 1986. 295# 296# From Thomas S. Mullaney (2008-02-11): 297# I think you're combining two subjects that need to treated 298# separately: daylight savings (which, you're correct, wasn't 299# implemented until the 1980s) and the unified time zone centered near 300# Beijing (which was implemented in 1949). Briefly, there was also a 301# "Lhasa Time" in Tibet and "Urumqi Time" in Xinjiang. The first was 302# ceased, and the second eventually recognized (again, in the 1980s). 303# 304# From Paul Eggert (2008-06-30): 305# There seems to be a good chance China switched to a single time zone in 1949 306# rather than in 1980 as Shanks & Pottenger have it, but we don't have a 307# reliable documentary source saying so yet, so for now we still go with 308# Shanks & Pottenger. 309 310# Zone NAME GMTOFF RULES FORMAT [UNTIL] 311# Changbai Time ("Long-white Time", Long-white = Heilongjiang area) 312# Heilongjiang (except Mohe county), Jilin 313Zone Asia/Harbin 8:26:44 - LMT 1928 # or Haerbin 314 8:30 - CHAT 1932 Mar # Changbai Time 315 8:00 - CST 1940 316 9:00 - CHAT 1966 May 317 8:30 - CHAT 1980 May 318 8:00 PRC C%sT 319# Zhongyuan Time ("Central plain Time") 320# most of China 321Zone Asia/Shanghai 8:05:52 - LMT 1928 322 8:00 Shang C%sT 1949 323 8:00 PRC C%sT 324# Long-shu Time (probably due to Long and Shu being two names of that area) 325# Guangxi, Guizhou, Hainan, Ningxia, Sichuan, Shaanxi, and Yunnan; 326# most of Gansu; west Inner Mongolia; west Qinghai; and the Guangdong 327# counties Deqing, Enping, Kaiping, Luoding, Taishan, Xinxing, 328# Yangchun, Yangjiang, Yu'nan, and Yunfu. 329Zone Asia/Chongqing 7:06:20 - LMT 1928 # or Chungking 330 7:00 - LONT 1980 May # Long-shu Time 331 8:00 PRC C%sT 332# Xin-zang Time ("Xinjiang-Tibet Time") 333# The Gansu counties Aksay, Anxi, Dunhuang, Subei; west Qinghai; 334# the Guangdong counties Xuwen, Haikang, Suixi, Lianjiang, 335# Zhanjiang, Wuchuan, Huazhou, Gaozhou, Maoming, Dianbai, and Xinyi; 336# east Tibet, including Lhasa, Chamdo, Shigaise, Jimsar, Shawan and Hutubi; 337# east Xinjiang, including Urumqi, Turpan, Karamay, Korla, Minfeng, Jinghe, 338# Wusu, Qiemo, Xinyan, Wulanwusu, Jinghe, Yumin, Tacheng, Tuoli, Emin, 339# Shihezi, Changji, Yanqi, Heshuo, Tuokexun, Tulufan, Shanshan, Hami, 340# Fukang, Kuitun, Kumukuli, Miquan, Qitai, and Turfan. 341Zone Asia/Urumqi 5:50:20 - LMT 1928 # or Urumchi 342 6:00 - URUT 1980 May # Urumqi Time 343 8:00 PRC C%sT 344# Kunlun Time 345# West Tibet, including Pulan, Aheqi, Shufu, Shule; 346# West Xinjiang, including Aksu, Atushi, Yining, Hetian, Cele, Luopu, Nileke, 347# Zhaosu, Tekesi, Gongliu, Chabuchaer, Huocheng, Bole, Pishan, Suiding, 348# and Yarkand. 349Zone Asia/Kashgar 5:03:56 - LMT 1928 # or Kashi or Kaxgar 350 5:30 - KAST 1940 # Kashgar Time 351 5:00 - KAST 1980 May 352 8:00 PRC C%sT 353 354# Hong Kong (Xianggang) 355# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S 356Rule HK 1946 only - Apr 20 3:30 1:00 S 357Rule HK 1946 only - Dec 1 3:30 0 - 358Rule HK 1947 only - Apr 13 3:30 1:00 S 359Rule HK 1947 only - Dec 30 3:30 0 - 360Rule HK 1948 only - May 2 3:30 1:00 S 361Rule HK 1948 1952 - Oct lastSun 3:30 0 - 362Rule HK 1949 1953 - Apr Sun>=1 3:30 1:00 S 363Rule HK 1953 only - Nov 1 3:30 0 - 364Rule HK 1954 1964 - Mar Sun>=18 3:30 1:00 S 365Rule HK 1954 only - Oct 31 3:30 0 - 366Rule HK 1955 1964 - Nov Sun>=1 3:30 0 - 367Rule HK 1965 1977 - Apr Sun>=16 3:30 1:00 S 368Rule HK 1965 1977 - Oct Sun>=16 3:30 0 - 369Rule HK 1979 1980 - May Sun>=8 3:30 1:00 S 370Rule HK 1979 1980 - Oct Sun>=16 3:30 0 - 371# Zone NAME GMTOFF RULES FORMAT [UNTIL] 372Zone Asia/Hong_Kong 7:36:36 - LMT 1904 Oct 30 373 8:00 HK HK%sT 374 375 376############################################################################### 377 378# Taiwan 379 380# Shanks & Pottenger write that Taiwan observed DST during 1945, when it 381# was still controlled by Japan.
