For more, please see # the file CONTRIBUTING in the tz distribution. # From Paul Eggert (2014-08-12): # This file contains data outside the normal scope of the tz database, # in that its zones do not differ from normal tz zones after 1970. # Links in this file point to zones in this file, superseding links in # the file 'backward'. # Although zones in this file may be of some use for analyzing # pre-1970 time stamps, they are less reliable, cover only a tiny # sliver of the pre-1970 era, and cannot feasibly be improved to cover # most of the era. Because the zones are out of normal scope for the # database, less effort is put into maintaining this file. Many of # the zones were formerly in other source files, but were removed or # replaced by links as their data entries were questionable and/or they # differed from other zones only in pre-1970 time stamps. # Unless otherwise specified, the source for the data is the following, # which does not itself cite sources and is often wrong: # # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition), # San Diego: ACS Publications, Inc. (2003). # This file is not intended to be compiled standalone, as it # assumes rules from other files. In the tz distribution, use # 'make posix_packrat' to compile this file. # Zones are sorted by zone name. Each zone is preceded by the # name of the country that the zone is in, along with any other # commentary and rules associated with the entry. # # As explained in the zic man page, the zone columns are: # Zone NAME GMTOFF RULES FORMAT [UNTIL] # Mali (southern) Zone Africa/Bamako -0:32:00 - LMT 1912 0:00 - GMT 1934 Feb 26 -1:00 - WAT 1960 Jun 20 0:00 - GMT # Central African Republic Zone Africa/Bangui 1:14:20 - LMT 1912 1:00 - WAT # Gambia Zone Africa/Banjul -1:06:36 - LMT 1912 -1:06:36 - BMT 1935 # Banjul Mean Time -1:00 - WAT 1964 0:00 - GMT
