Shanks and Rique Pottenger, The International Atlas (6th edition), 13 # San Diego: ACS Publications, Inc. (2003). 14 # Unfortunately this book contains many errors and cites no sources. 15 # 16 # Many years ago Gwillim Law wrote that a good source 17 # for time zone data was 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. Except where otherwise noted, 21 # IATA SSIM is the source for entries after 1990. 22 # 23 # Another source occasionally used is Edward W. Whitman, World Time Differences, 24 # Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which 25 # I found in the UCLA library. 26 # 27 # For data circa 1899, a common source is: 28 # Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94. 29 # https://www.jstor.org/stable/1774359 30 # 31 # A reliable and entertaining source about time zones is 32 # Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997). 33 # 34 # European-style abbreviations are commonly used along the Mediterranean. 35 # For sub-Saharan Africa abbreviations were less standardized. 36 # Previous editions of this database used WAT, CAT, SAT, and EAT 37 # for UT +00 through +03, respectively, 38 # but in 1997 Mark R V Murray reported that 39 # 'SAST' is the official abbreviation for +02 in the country of South Africa, 40 # 'CAT' is commonly used for +02 in countries north of South Africa, and 41 # 'WAT' is probably the best name for +01, as the common phrase for 42 # the area that includes Nigeria is "West Africa". 43 # 44 # To summarize, the following abbreviations seemed to have some currency: 45 # +00 GMT Greenwich Mean Time 46 # +02 CAT Central Africa Time 47 # +02 SAST South Africa Standard Time 48 # and Murray suggested the following abbreviation: 49 # +01 WAT West Africa Time 50 # Murray's suggestion seems to have caught on in news reports and the like. 51 # I vaguely recall 'WAT' also being used for -01 in the past but 52 # cannot now come up with solid citations. 53 # 54 # I invented the following abbreviations; corrections are welcome! 55 # +02 WAST West Africa Summer Time 56 # +03 CAST Central Africa Summer Time (no longer used) 57 # +03 SAST South Africa Summer Time (no longer used) 58 # +03 EAT East Africa Time 59 # 'EAT' also seems to have caught on; the others are rare but are paired 60 # with better-attested non-DST abbreviations. 61 62 # Algeria 63 # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S 64 Rule Algeria 1916 only - Jun 14 23:00s 1:00 S 65 Rule Algeria 1916 1919 - Oct Sun>=1 23:00s 0 - 66 Rule Algeria 1917 only - Mar 24 23:00s 1:00 S 67 Rule Algeria 1918 only - Mar 9 23:00s 1:00 S 68 Rule Algeria 1919 only - Mar 1 23:00s 1:00 S 69 Rule Algeria 1920 only - Feb 14 23:00s 1:00 S 70 Rule Algeria 1920 only - Oct 23 23:00s 0 - 71 Rule Algeria 1921 only - Mar 14 23:00s 1:00 S 72 Rule Algeria 1921 only - Jun 21 23:00s 0 - 73 Rule Algeria 1939 only - Sep 11 23:00s 1:00 S 74 Rule Algeria 1939 only - Nov 19 1:00 0 - 75 Rule Algeria 1944 1945 - Apr Mon>=1 2:00 1:00 S 76 Rule Algeria 1944 only - Oct 8 2:00 0 - 77 Rule Algeria 1945 only - Sep 16 1:00 0 - 78 Rule Algeria 1971 only - Apr 25 23:00s 1:00 S 79 Rule Algeria 1971 only - Sep 26 23:00s 0 - 80 Rule Algeria 1977 only - May 6 0:00 1:00 S 81 Rule Algeria 1977 only - Oct 21 0:00 0 - 82 Rule Algeria 1978 only - Mar 24 1:00 1:00 S 83 Rule Algeria 1978 only - Sep 22 3:00 0 - 84 Rule Algeria 1980 only - Apr 25 0:00 1:00 S 85 Rule Algeria 1980 only - Oct 31 2:00 0 - 86 # Shanks & Pottenger give 0:09:20 for Paris Mean Time; go with Howse's 87 # more precise 0:09:21. 88 # Zone NAME GMTOFF RULES FORMAT [UNTIL] 89 Zone Africa/Algiers 0:12:12 - LMT 1891 Mar 15 0:01 90 0:09:21 - PMT 1911 Mar 11 # Paris Mean Time 91 0:00 Algeria WE%sT 1940 Feb 25 2:00 92 1:00 Algeria CE%sT 1946 Oct 7 93 0:00 - WET 1956 Jan 29 94 1:00 - CET 1963 Apr 14 95 0:00 Algeria WE%sT 1977 Oct 21 96 1:00 Algeria CE%sT 1979 Oct 26 97 0:00 Algeria WE%sT 1981 May 98 1:00 - CET 99 100 # Angola 101 # Benin 102 # See Africa/Lagos. 103 104 # Botswana 105 # See Africa/Maputo. 106 107 # Burkina Faso 108 # See Africa/Abidjan. 109 110 # Burundi 111 # See Africa/Maputo. 112 113 # Cameroon 114 # See Africa/Lagos. 115 116 # Cape Verde / Cabo Verde 117 # 118 # Shanks gives 1907 for the transition to +02. 119 # Perhaps the 1911-05-26 Portuguese decree 120 # https://dre.pt/pdf1sdip/1911/05/12500/23132313.pdf 121 # merely made it official?
