  22 # tzdb data for ships at sea and other miscellany
  23 
  24 # This file is in the public domain, so clarified as of
  25 # 2009-05-17 by Arthur David Olson.
  26 
  27 # These entries are mostly present for historical reasons, so that
  28 # people in areas not otherwise covered by the tz files could "zic -l"
  29 # to a timezone that was right for their area.  These days, the
  30 # tz files cover almost all the inhabited world, and the only practical
  31 # need now for the entries that are not on UTC are for ships at sea
  32 # that cannot use POSIX TZ settings.
  33 
  34 # Starting with POSIX 1003.1-2001, the entries below are all
  35 # unnecessary as settings for the TZ environment variable.  E.g.,
  36 # instead of TZ='Etc/GMT+4' one can use the POSIX setting TZ='<-04>+4'.
  37 #
  38 # Do not use a POSIX TZ setting like TZ='GMT+4', which is four hours
  39 # behind GMT but uses the completely misleading abbreviation "GMT".

  44 # The following link uses older naming conventions,
  45 # but it belongs here, not in the file 'backward',
  46 # as functions like gmtime load the "GMT" file to handle leap seconds properly.
  47 # We want this to work even on installations that omit the other older names.

  58 # Be consistent with POSIX TZ settings in the Zone names,
  59 # even though this is the opposite of what many people expect.
  60 # POSIX has positive signs west of Greenwich, but many people expect
  61 # positive signs east of Greenwich.  For example, TZ='Etc/GMT+4' uses
  62 # the abbreviation "-04" and corresponds to 4 hours behind UT
  63 # (i.e. west of Greenwich) even though many people would expect it to
  64 # mean 4 hours ahead of UT (i.e. east of Greenwich).
  65 
  66 # Earlier incarnations of this package were not POSIX-compliant,
  67 # and had lines such as
  68 #               Zone    GMT-12          -12     -       GMT-1200
  69 # We did not want things to change quietly if someone accustomed to the old
  70 # way does a
  71 #               zic -l GMT-12
  72 # so we moved the names into the Etc subdirectory.
  73 # Also, the time zone abbreviations are now compatible with %z.
