   5 # to a time zone that was right for their area.  These days, the
   6 # tz files cover almost all the inhabited world, so there's little
   7 # need now for the entries that are not on UTC.

  27 # We use POSIX-style signs in the Zone names and the output abbreviations,
  28 # even though this is the opposite of what many people expect.
  29 # POSIX has positive signs west of Greenwich, but many people expect
  30 # positive signs east of Greenwich.  For example, TZ='Etc/GMT+4' uses
  31 # the abbreviation "GMT+4" and corresponds to 4 hours behind UTC
  32 # (i.e. west of Greenwich) even though many people would expect it to
  33 # mean 4 hours ahead of UTC (i.e. east of Greenwich).
  34 #
  35 # In the draft 5 of POSIX 1003.1-200x, the angle bracket notation
  36 # (which is not yet supported by the tz code) allows for
  37 # TZ='<GMT-4>+4'; if you want time zone abbreviations conforming to
  38 # ISO 8601 you can use TZ='<-0400>+4'.  Thus the commonly-expected
  39 # offset is kept within the angle bracket (and is used for display)
  40 # while the POSIX sign is kept outside the angle bracket (and is used
  41 # for calculation).
  42 #
  43 # Do not use a TZ setting like TZ='GMT+4', which is four hours behind
  44 # GMT but uses the completely misleading abbreviation "GMT".

  46 # Earlier incarnations of this package were not POSIX-compliant,

  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.
