1# Zones that go back beyond the scope of the tz database 2 3# This file is in the public domain. 4 5# This file is by no means authoritative; if you think you know 6# better, go ahead and edit it (and please send any changes to 7# tz@iana.org for general use in the future). For more, please see 8# the file CONTRIBUTING in the tz distribution. 9 10 11# From Paul Eggert (2014-10-31): 12 13# This file contains data outside the normal scope of the tz database, 14# in that its zones do not differ from normal tz zones after 1970. 15# Links in this file point to zones in this file, superseding links in 16# the file 'backward'. 17 18# Although zones in this file may be of some use for analyzing 19# pre-1970 timestamps, they are less reliable, cover only a tiny 20# sliver of the pre-1970 era, and cannot feasibly be improved to cover 21# most of the era. Because the zones are out of normal scope for the 22# database, less effort is put into maintaining this file. Many of 23# the zones were formerly in other source files, but were removed or 24# replaced by links as their data entries were questionable and/or they 25# differed from other zones only in pre-1970 timestamps. 26 27# Unless otherwise specified, the source for data through 1990 is: 28# Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition), 29# San Diego: ACS Publications, Inc. (2003). 30# Unfortunately this book contains many errors and cites no sources. 31 32# This file is not intended to be compiled standalone, as it 33# assumes rules from other files. In the tz distribution, use 34# 'make PACKRATDATA=backzone zones' to compile and install this file. 35 36# Zones are sorted by zone name. Each zone is preceded by the 37# name of the country that the zone is in, along with any other 38# commentary and rules associated with the entry. 39# 40# As explained in the zic man page, the zone columns are: 41# Zone NAME STDOFF RULES FORMAT [UNTIL] 42 43# Ethiopia 44# From Paul Eggert (2014-07-31): 45# Like the Swahili of Kenya and Tanzania, many Ethiopians keep a 46# 12-hour clock starting at our 06:00, so their "8 o'clock" is our 47# 02:00 or 14:00. Keep this in mind when you ask the time in Amharic. 48# 49# Shanks & Pottenger write that Ethiopia had six narrowly-spaced time 50# zones between 1870 and 1890, that they merged to 38E50 (2:35:20) in 51# 1890, and that they switched to 3:00 on 1936-05-05. Perhaps 38E50 52# was for Adis Dera. Quite likely the Shanks data entries are wrong 53# anyway. 54Zone Africa/Addis_Ababa 2:34:48 - LMT 1870 55 2:35:20 - ADMT 1936 May 5 # Adis Dera MT 56 3:00 - EAT 57 58# Eritrea 59Zone Africa/Asmara 2:35:32 - LMT 1870 60 2:35:32 - AMT 1890 # Asmara Mean Time 61 2:35:20 - ADMT 1936 May 5 # Adis Dera MT 62 3:00 - EAT 63Link Africa/Asmara Africa/Asmera 64 65# Mali (southern) 66Zone Africa/Bamako -0:32:00 - LMT 1912 67 0:00 - GMT 1934 Feb 26 68 -1:00 - -01 1960 Jun 20 69 0:00 - GMT 70 71# Central African Republic 72Zone Africa/Bangui 1:14:20 - LMT 1912 73 1:00 - WAT 74 75# Gambia 76Zone Africa/Banjul -1:06:36 - LMT 1912 77 -1:06:36 - BMT 1935 # Banjul Mean Time 78 -1:00 - -01 1964 79 0:00 - GMT 80 81# Malawi 82Zone Africa/Blantyre 2:20:00 - LMT 1903 Mar 83 2:00 - CAT 84 85# Republic of the Congo 86Zone Africa/Brazzaville 1:01:08 - LMT 1912 87 1:00 - WAT 88 89# Burundi 90Zone Africa/Bujumbura 1:57:28 - LMT 1890 91 2:00 - CAT 92 93# Guinea 94Zone Africa/Conakry -0:54:52 - LMT 1912 95 0:00 - GMT 1934 Feb 26 96 -1:00 - -01 1960 97 0:00 - GMT 98 99# Senegal 100Zone Africa/Dakar -1:09:44 - LMT 1912 101 -1:00 - -01 1941 Jun 102 0:00 - GMT 103 104# Tanzania 105Zone Africa/Dar_es_Salaam 2:37:08 - LMT 1931 106 3:00 - EAT 1948 107 2:45 - +0245 1961 108 3:00 - EAT 109 110# Djibouti 111Zone Africa/Djibouti 2:52:36 - LMT 1911 Jul 112 3:00 - EAT 113 114# Cameroon 115# Whitman says they switched to 1:00 in 1920; go with Shanks & Pottenger. 116Zone Africa/Douala 0:38:48 - LMT 1912 117 1:00 - WAT 118# Sierra Leone 119# From Paul Eggert (2014-08-12): 120# The following table is from Shanks & Pottenger, but it can't be right. 121# Whitman gives Mar 31 - Aug 31 for 1931 on. 122# The International Hydrographic Bulletin, 1932-33, p 63 says that 123# Sierra Leone would advance its clocks by 20 minutes on 1933-10-01. 124# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S 125Rule SL 1935 1942 - Jun 1 0:00 0:40 -0020 126Rule SL 1935 1942 - Oct 1 0:00 0 -01 127Rule SL 1957 1962 - Jun 1 0:00 1:00 +01 128Rule SL 1957 1962 - Sep 1 0:00 0 GMT 129Zone Africa/Freetown -0:53:00 - LMT 1882 130 -0:53:00 - FMT 1913 Jun # Freetown Mean Time 131 -1:00 SL %s 1957 132 0:00 SL GMT/+01 133 134# Botswana 135# From Paul Eggert (2013-02-21): 136# Milne says they were regulated by the Cape Town Signal in 1899; 137# assume they switched to 2:00 when Cape Town did. 138Zone Africa/Gaborone 1:43:40 - LMT 1885 139 1:30 - SAST 1903 Mar 140 2:00 - CAT 1943 Sep 19 2:00 141 2:00 1:00 CAST 1944 Mar 19 2:00 142 2:00 - CAT 143 144# Zimbabwe 145Zone Africa/Harare 2:04:12 - LMT 1903 Mar 146 2:00 - CAT 147 148# Uganda 149Zone Africa/Kampala 2:09:40 - LMT 1928 Jul 150 3:00 - EAT 1930 151 2:30 - +0230 1948 152 2:45 - +0245 1957 153 3:00 - EAT 154 155# Rwanda 156Zone Africa/Kigali 2:00:16 - LMT 1935 Jun 157 2:00 - CAT 158 159# Democratic Republic of the Congo (west) 160Zone Africa/Kinshasa 1:01:12 - LMT 1897 Nov 9 161 1:00 - WAT 162 163# Gabon 164Zone Africa/Libreville 0:37:48 - LMT 1912 165 1:00 - WAT 166 167# Togo 168Zone Africa/Lome 0:04:52 - LMT 1893 169 0:00 - GMT 170 171# Angola 172# 173# From Paul Eggert (2018-02-16): 174# Shanks gives 1911-05-26 for the transition to WAT, 175# evidently confusing the date of the Portuguese decree 176# (see Europe/Lisbon) with the date that it took effect. 177# 178Zone Africa/Luanda 0:52:56 - LMT 1892 179 0:52:04 - LMT 1911 Dec 31 23:00u # Luanda MT? 180 1:00 - WAT 181 182# Democratic Republic of the Congo (east) 183Zone Africa/Lubumbashi 1:49:52 - LMT 1897 Nov 9 184 2:00 - CAT 185 186# Zambia 187Zone Africa/Lusaka 1:53:08 - LMT 1903 Mar 188 2:00 - CAT 189 190# Equatorial Guinea 191# 192# Although Shanks says that Malabo switched from UT +00 to +01 on 1963-12-15, 193# a Google Books search says that London Calling, Issues 432-465 (1948), p 19, 194# says that Spanish Guinea was at +01 back then.
