These days, the 8 # tz files cover almost all the inhabited world, and the only practical 9 # need now for the entries that are not on UTC are for ships at sea 10 # that cannot use POSIX TZ settings. 11 12 Zone Etc/GMT 0 - GMT 13 Zone Etc/UTC 0 - UTC 14 Zone Etc/UCT 0 - UCT 15 16 # The following link uses older naming conventions, 17 # but it belongs here, not in the file `backward', 18 # as functions like gmtime load the "GMT" file to handle leap seconds properly. 19 # We want this to work even on installations that omit the other older names. 20 Link Etc/GMT GMT 21 22 Link Etc/UTC Etc/Universal 23 Link Etc/UTC Etc/Zulu 24 25 Link Etc/GMT Etc/Greenwich 26 Link Etc/GMT Etc/GMT-0 27 Link Etc/GMT Etc/GMT+0 28 Link Etc/GMT Etc/GMT0 29 30 # We use POSIX-style signs in the Zone names and the output abbreviations, 31 # even though this is the opposite of what many people expect. 32 # POSIX has positive signs west of Greenwich, but many people expect 33 # positive signs east of Greenwich. For example, TZ='Etc/GMT+4' uses 34 # the abbreviation "GMT+4" and corresponds to 4 hours behind UT 35 # (i.e. west of Greenwich) even though many people would expect it to 36 # mean 4 hours ahead of UT (i.e. east of Greenwich). 37 # 38 # In the draft 5 of POSIX 1003.1-200x, the angle bracket notation allows for 39 # TZ='<GMT-4>+4'; if you want time zone abbreviations conforming to 40 # ISO 8601 you can use TZ='<-0400>+4'. Thus the commonly-expected 41 # offset is kept within the angle bracket (and is used for display) 42 # while the POSIX sign is kept outside the angle bracket (and is used 43 # for calculation). 44 # 45 # Do not use a TZ setting like TZ='GMT+4', which is four hours behind 46 # GMT but uses the completely misleading abbreviation "GMT". 47 48 # Earlier incarnations of this package were not POSIX-compliant, 49 # and had lines such as 50 # Zone GMT-12 -12 - GMT-1200 51 # We did not want things to change quietly if someone accustomed to the old 52 # way does a 53 # zic -l GMT-12 54 # so we moved the names into the Etc subdirectory. 55 56 Zone Etc/GMT-14 14 - GMT-14 # 14 hours ahead of GMT 57 Zone Etc/GMT-13 13 - GMT-13 58 Zone Etc/GMT-12 12 - GMT-12 59 Zone Etc/GMT-11 11 - GMT-11 60 Zone Etc/GMT-10 10 - GMT-10 61 Zone Etc/GMT-9 9 - GMT-9 62 Zone Etc/GMT-8 8 - GMT-8 63 Zone Etc/GMT-7 7 - GMT-7 64 Zone Etc/GMT-6 6 - GMT-6 65 Zone Etc/GMT-5 5 - GMT-5 66 Zone Etc/GMT-4 4 - GMT-4 67 Zone Etc/GMT-3 3 - GMT-3 68 Zone Etc/GMT-2 2 - GMT-2 69 Zone Etc/GMT-1 1 - GMT-1 70 Zone Etc/GMT+1 -1 - GMT+1 71 Zone Etc/GMT+2 -2 - GMT+2 72 Zone Etc/GMT+3 -3 - GMT+3 73 Zone Etc/GMT+4 -4 - GMT+4 74 Zone Etc/GMT+5 -5 - GMT+5 75 Zone Etc/GMT+6 -6 - GMT+6 76 Zone Etc/GMT+7 -7 - GMT+7 77 Zone Etc/GMT+8 -8 - GMT+8 78 Zone Etc/GMT+9 -9 - GMT+9 79 Zone Etc/GMT+10 -10 - GMT+10 80 Zone Etc/GMT+11 -11 - GMT+11 81 Zone Etc/GMT+12 -12 - GMT+12
