1 # tzdb data for ships at sea and other miscellany 2 3 # This file is in the public domain, so clarified as of 4 # 2009-05-17 by Arthur David Olson. 5 6 # These entries are mostly present for historical reasons, so that 7 # people in areas not otherwise covered by the tz files could "zic -l" 8 # to a timezone that was right for their area. These days, the 9 # tz files cover almost all the inhabited world, and the only practical 10 # need now for the entries that are not on UTC are for ships at sea 11 # that cannot use POSIX TZ settings. 12 13 # Starting with POSIX 1003.1-2001, the entries below are all 14 # unnecessary as settings for the TZ environment variable. E.g., 15 # instead of TZ='Etc/GMT+4' one can use the POSIX setting TZ='<-04>+4'. 16 # 17 # Do not use a POSIX TZ setting like TZ='GMT+4', which is four hours 18 # behind GMT but uses the completely misleading abbreviation "GMT". 19 20 Zone Etc/GMT 0 - GMT 21 Zone Etc/UTC 0 - UTC 22 Zone Etc/UCT 0 - UCT 23 24 # The following link uses older naming conventions, 25 # but it belongs here, not in the file 'backward', 26 # as functions like gmtime load the "GMT" file to handle leap seconds properly. 27 # We want this to work even on installations that omit the other older names. 28 Link Etc/GMT GMT 29 30 Link Etc/UTC Etc/Universal 31 Link Etc/UTC Etc/Zulu 32 33 Link Etc/GMT Etc/Greenwich 34 Link Etc/GMT Etc/GMT-0 35 Link Etc/GMT Etc/GMT+0 36 Link Etc/GMT Etc/GMT0 37 38 # Be consistent with POSIX TZ settings in the Zone names, 39 # even though this is the opposite of what many people expect. 40 # POSIX has positive signs west of Greenwich, but many people expect 41 # positive signs east of Greenwich. For example, TZ='Etc/GMT+4' uses 42 # the abbreviation "-04" and corresponds to 4 hours behind UT 43 # (i.e. west of Greenwich) even though many people would expect it to 44 # mean 4 hours ahead of UT (i.e. east of Greenwich). 45 46 # Earlier incarnations of this package were not POSIX-compliant, 47 # and had lines such as 48 # Zone GMT-12 -12 - GMT-1200 49 # We did not want things to change quietly if someone accustomed to the old 50 # way does a 51 # zic -l GMT-12 52 # so we moved the names into the Etc subdirectory. 53 # Also, the time zone abbreviations are now compatible with %z. 54 55 Zone Etc/GMT-14 14 - +14 56 Zone Etc/GMT-13 13 - +13 57 Zone Etc/GMT-12 12 - +12 58 Zone Etc/GMT-11 11 - +11 59 Zone Etc/GMT-10 10 - +10 60 Zone Etc/GMT-9 9 - +09 61 Zone Etc/GMT-8 8 - +08 62 Zone Etc/GMT-7 7 - +07 63 Zone Etc/GMT-6 6 - +06 64 Zone Etc/GMT-5 5 - +05 65 Zone Etc/GMT-4 4 - +04 66 Zone Etc/GMT-3 3 - +03 67 Zone Etc/GMT-2 2 - +02 68 Zone Etc/GMT-1 1 - +01 69 Zone Etc/GMT+1 -1 - -01 70 Zone Etc/GMT+2 -2 - -02 71 Zone Etc/GMT+3 -3 - -03 72 Zone Etc/GMT+4 -4 - -04 73 Zone Etc/GMT+5 -5 - -05 74 Zone Etc/GMT+6 -6 - -06 75 Zone Etc/GMT+7 -7 - -07 76 Zone Etc/GMT+8 -8 - -08 77 Zone Etc/GMT+9 -9 - -09 78 Zone Etc/GMT+10 -10 - -10 79 Zone Etc/GMT+11 -11 - -11 80 Zone Etc/GMT+12 -12 - -12
