1 # tzdb data for ships at sea and other miscellany
3 # This file is in the public domain, so clarified as of
4 # 2009-05-17 by Arthur David Olson.
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.
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'.
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".
23 # The following link uses older naming conventions,
24 # but it belongs here, not in the file 'backward',
25 # as functions like gmtime load the "UTC" file to handle leap seconds properly.
26 # We want this to work even on installations that omit the other older names.
29 Link Etc/UTC Etc/Universal
32 Link Etc/GMT Etc/Greenwich
33 Link Etc/GMT Etc/GMT-0
34 Link Etc/GMT Etc/GMT+0
37 # Be consistent with POSIX TZ settings in the Zone names,
38 # even though this is the opposite of what many people expect.
39 # POSIX has positive signs west of Greenwich, but many people expect
40 # positive signs east of Greenwich. For example, TZ='Etc/GMT+4' uses
41 # the abbreviation "-04" and corresponds to 4 hours behind UT
42 # (i.e. west of Greenwich) even though many people would expect it to
43 # mean 4 hours ahead of UT (i.e. east of Greenwich).
45 # Earlier incarnations of this package were not POSIX-compliant,
46 # and had lines such as
47 # Zone GMT-12 -12 - GMT-1200
48 # We did not want things to change quietly if someone accustomed to the old
51 # so we moved the names into the Etc subdirectory.
52 # Also, the time zone abbreviations are now compatible with %z.
