For more, please see 9 # the file CONTRIBUTING in the tz distribution. 10 11 # From Paul Eggert (2018-05-27): 12 # 13 # Unless otherwise specified, the source for data through 1990 is: 14 # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition), 15 # San Diego: ACS Publications, Inc. (2003). 16 # Unfortunately this book contains many errors and cites no sources. 17 # 18 # Many years ago Gwillim Law wrote that a good source 19 # for time zone data was the International Air Transport 20 # Association's Standard Schedules Information Manual (IATA SSIM), 21 # published semiannually. Law sent in several helpful summaries 22 # of the IATA's data after 1990. Except where otherwise noted, 23 # IATA SSIM is the source for entries after 1990. 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 # For data circa 1899, a common source is: 30 # Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94. 31 # https://www.jstor.org/stable/1774359 32 # 33 # European-style abbreviations are commonly used along the Mediterranean. 34 # For sub-Saharan Africa abbreviations were less standardized. 35 # Previous editions of this database used WAT, CAT, SAT, and EAT 36 # for UT +00 through +03, respectively, 37 # but in 1997 Mark R V Murray reported that 38 # 'SAST' is the official abbreviation for +02 in the country of South Africa, 39 # 'CAT' is commonly used for +02 in countries north of South Africa, and 40 # 'WAT' is probably the best name for +01, as the common phrase for 41 # the area that includes Nigeria is "West Africa". 42 # 43 # To summarize, the following abbreviations seemed to have some currency: 44 # +00 GMT Greenwich Mean Time 45 # +02 CAT Central Africa Time 46 # +02 SAST South Africa Standard Time 47 # and Murray suggested the following abbreviation: 48 # +01 WAT West Africa Time 49 # Murray's suggestion seems to have caught on in news reports and the like. 50 # I vaguely recall 'WAT' also being used for -01 in the past but 51 # cannot now come up with solid citations. 52 # 53 # I invented the following abbreviations in the 1990s: 54 # +02 WAST West Africa Summer Time 55 # +03 CAST Central Africa Summer Time 56 # +03 SAST South Africa Summer Time 57 # +03 EAT East Africa Time 58 # 'EAT' seems to have caught on and is in current timestamps, and though 59 # the other abbreviations are rarer and are only in past timestamps, 60 # they are paired with better-attested non-DST abbreviations. 61 # Corrections are welcome. 62 63 # Algeria 64 # Rule NAME FROM TO - IN ON AT SAVE LETTER/S 65 Rule Algeria 1916 only - Jun 14 23:00s 1:00 S 66 Rule Algeria 1916 1919 - Oct Sun>=1 23:00s 0 - 67 Rule Algeria 1917 only - Mar 24 23:00s 1:00 S 68 Rule Algeria 1918 only - Mar 9 23:00s 1:00 S 69 Rule Algeria 1919 only - Mar 1 23:00s 1:00 S 70 Rule Algeria 1920 only - Feb 14 23:00s 1:00 S 71 Rule Algeria 1920 only - Oct 23 23:00s 0 - 72 Rule Algeria 1921 only - Mar 14 23:00s 1:00 S 73 Rule Algeria 1921 only - Jun 21 23:00s 0 - 74 Rule Algeria 1939 only - Sep 11 23:00s 1:00 S 75 Rule Algeria 1939 only - Nov 19 1:00 0 - 76 Rule Algeria 1944 1945 - Apr Mon>=1 2:00 1:00 S 77 Rule Algeria 1944 only - Oct 8 2:00 0 - 78 Rule Algeria 1945 only - Sep 16 1:00 0 - 79 Rule Algeria 1971 only - Apr 25 23:00s 1:00 S 80 Rule Algeria 1971 only - Sep 26 23:00s 0 - 81 Rule Algeria 1977 only - May 6 0:00 1:00 S 82 Rule Algeria 1977 only - Oct 21 0:00 0 - 83 Rule Algeria 1978 only - Mar 24 1:00 1:00 S 84 Rule Algeria 1978 only - Sep 22 3:00 0 - 85 Rule Algeria 1980 only - Apr 25 0:00 1:00 S 86 Rule Algeria 1980 only - Oct 31 2:00 0 - 87 # See Europe/Paris for PMT-related transitions. 88 # Zone NAME STDOFF RULES FORMAT [UNTIL] 89 Zone Africa/Algiers 0:12:12 - LMT 1891 Mar 16 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 # Zone NAME STDOFF RULES FORMAT [UNTIL] 102 Zone Africa/Luanda 0:52:56 - LMT 1892 103 0:52:04 - LMT 1911 Dec 31 23:00u # Luanda MT?
