1 # This file is in the public domain, so clarified as of 2 # 2009-05-17 by Arthur David Olson. 3 4 # These entries are mostly present for historical reasons, so that 5 # people in areas not otherwise covered by the tz files could "zic -l" 6 # to a time zone that was right for their area. These days, the 7 # tz files cover almost all the inhabited world, and the only practical 8 # need now for the entries that are not on UTC are for ships at sea 9 # that cannot use POSIX TZ settings. 10 11 # Starting with POSIX 1003.1-2001, the entries below are all 12 # unnecessary as settings for the TZ environment variable. E.g., 13 # instead of TZ='Etc/GMT+4' one can use the POSIX setting TZ='<-04>+4'. 14 # 15 # Do not use a POSIX TZ setting like TZ='GMT+4', which is four hours 16 # behind GMT but uses the completely misleading abbreviation "GMT". 17 18 Zone Etc/GMT 0 - GMT 19 Zone Etc/UTC 0 - UTC 20 Zone Etc/UCT 0 - UCT 21 22 # The following link uses older naming conventions, 23 # but it belongs here, not in the file 'backward', 24 # as functions like gmtime load the "GMT" file to handle leap seconds properly. 25 # We want this to work even on installations that omit the other older names. 26 Link Etc/GMT GMT 27 28 Link Etc/UTC Etc/Universal 29 Link Etc/UTC Etc/Zulu 30 31 Link Etc/GMT Etc/Greenwich 32 Link Etc/GMT Etc/GMT-0 33 Link Etc/GMT Etc/GMT+0 34 Link Etc/GMT Etc/GMT0 35 36 # Be consistent with POSIX TZ settings in the Zone names, 37 # even though this is the opposite of what many people expect. 38 # POSIX has positive signs west of Greenwich, but many people expect 39 # positive signs east of Greenwich.
