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 time zone 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.
17 # The following link uses older naming conventions,
18 # but it belongs here, not in the file `backward',
19 # as functions like gmtime load the "GMT" file to handle leap seconds properly.
20 # We want this to work even on installations that omit the other older names.

31 # We use POSIX-style signs in the Zone names and the output abbreviations,
32 # even though this is the opposite of what many people expect.
33 # POSIX has positive signs west of Greenwich, but many people expect
34 # positive signs east of Greenwich. For example, TZ='Etc/GMT+4' uses
35 # the abbreviation "GMT+4" and corresponds to 4 hours behind UTC
36 # (i.e. west of Greenwich) even though many people would expect it to
37 # mean 4 hours ahead of UTC (i.e. east of Greenwich).
39 # In the draft 5 of POSIX 1003.1-200x, the angle bracket notation
40 # (which is not yet supported by the tz code) allows for
41 # TZ='<GMT-4>+4'; if you want time zone abbreviations conforming to
42 # ISO 8601 you can use TZ='<-0400>+4'. Thus the commonly-expected
43 # offset is kept within the angle bracket (and is used for display)
44 # while the POSIX sign is kept outside the angle bracket (and is used
47 # Do not use a TZ setting like TZ='GMT+4', which is four hours behind
48 # GMT but uses the completely misleading abbreviation "GMT".
50 # Earlier incarnations of this package were not POSIX-compliant,
51 # and had lines such as
52 # Zone GMT-12 -12 - GMT-1200
53 # We did not want things to change quietly if someone accustomed to the old
56 # so we moved the names into the Etc subdirectory.
