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. # # For data circa 1899, a common source is: # Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94. # http://www.jstor.org/stable/1774359 # # A reliable and entertaining source about time zones is # Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997). # # Previous editions of this database used WAT, CAT, SAT, and EAT # for +0:00 through +3:00, respectively, # but Mark R V Murray reports that # 'SAST' is the official abbreviation for +2:00 in the country of South Africa, # 'CAT' is commonly used for +2:00 in countries north of South Africa, and # 'WAT' is probably the best name for +1:00, as the common phrase for # the area that includes Nigeria is "West Africa". # He has heard of "Western Sahara Time" for +0:00 but can find no reference. # # To make things confusing, 'WAT' seems to have been used for -1:00 long ago; # I'd guess that this was because people needed _some_ name for -1:00, # and at the time, far west Africa was the only major land area in -1:00. # This usage is now obsolete, as the last use of -1:00 on the African # mainland seems to have been 1976 in Western Sahara. # # To summarize, the following abbreviations seem to have some currency: # -1:00 WAT West Africa Time (no longer used) # 0:00 GMT Greenwich Mean Time # 2:00 CAT Central Africa Time # 2:00 SAST South Africa Standard Time # and Murray suggests the following abbreviation: # 1:00 WAT West Africa Time # I realize that this leads to 'WAT' being used for both -1:00 and 1:00 # for times before 1976, but this is the best I can think of # until we get more information. # # I invented the following abbreviations; corrections are welcome! # 2:00 WAST West Africa Summer Time # 2:30 BEAT British East Africa Time (no longer used) # 2:45 BEAUT British East Africa Unified Time (no longer used) # 3:00 CAST Central Africa Summer Time (no longer used) # 3:00 SAST South Africa Summer Time (no longer used) # 3:00 EAT East Africa Time # 4:00 EAST East Africa Summer Time (no longer used) # Algeria # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S Rule Algeria 1916 only - Jun 14 23:00s 1:00 S Rule Algeria 1916 1919 - Oct Sun>=1 23:00s 0 - Rule Algeria 1917 only - Mar 24 23:00s 1:00 S Rule Algeria 1918 only - Mar 9 23:00s 1:00 S Rule Algeria 1919 only - Mar 1 23:00s 1:00 S Rule Algeria 1920 only - Feb 14 23:00s 1:00 S Rule Algeria 1920 only - Oct 23 23:00s 0 - Rule Algeria 1921 only - Mar 14 23:00s 1:00 S Rule Algeria 1921 only - Jun 21 23:00s 0 - Rule Algeria 1939 only - Sep 11 23:00s 1:00 S Rule Algeria 1939 only - Nov 19 1:00 0 - Rule Algeria 1944 1945 - Apr Mon>=1 2:00 1:00 S Rule Algeria 1944 only - Oct 8 2:00 0 - Rule Algeria 1945 only - Sep 16 1:00 0 - Rule Algeria 1971 only - Apr 25 23:00s 1:00 S Rule Algeria 1971 only - Sep 26 23:00s 0 - Rule Algeria 1977 only - May 6 0:00 1:00 S Rule Algeria 1977 only - Oct 21 0:00 0 - Rule Algeria 1978 only - Mar 24 1:00 1:00 S Rule Algeria 1978 only - Sep 22 3:00 0 - Rule Algeria 1980 only - Apr 25 0:00 1:00 S Rule Algeria 1980 only - Oct 31 2:00 0 - # Shanks & Pottenger give 0:09:20 for Paris Mean Time; go with Howse's # more precise 0:09:21. # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Africa/Algiers 0:12:12 - LMT 1891 Mar 15 0:01 0:09:21 - PMT 1911 Mar 11 # Paris Mean Time 0:00 Algeria WE%sT 1940 Feb 25 2:00 1:00 Algeria CE%sT 1946 Oct 7 0:00 - WET 1956 Jan 29 1:00 - CET 1963 Apr 14 0:00 Algeria WE%sT 1977 Oct 21 1:00 Algeria CE%sT 1979 Oct 26 0:00 Algeria WE%sT 1981 May 1:00 - CET # Angola # Benin # See Africa/Lagos. # Botswana # From Paul Eggert (2013-02-21): # Milne says they were regulated by the Cape Town Signal in 1899; # assume they switched to 2:00 when Cape Town did. # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Africa/Gaborone 1:43:40 - LMT 1885 1:30 - SAST 1903 Mar 2:00 - CAT 1943 Sep 19 2:00 2:00 1:00 CAST 1944 Mar 19 2:00 2:00 - CAT # Burkina Faso # See Africa/Abidjan. # Burundi # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone Africa/Bujumbura 1:57:28 - LMT 1890 2:00 - CAT # Cameroon # See Africa/Lagos. # Cape Verde # # Shanks gives 1907 for the transition to CVT. # Perhaps the 1911-05-26 Portuguese decree # http://dre.pt/pdf1sdip/1911/05/12500/23132313.pdf # merely made it official?
