      4 The /usr/share/lib/zoneinfo/src directory contains zoneinfo timezone source
      5 files.  These source files have been compiled using zic(1M) to create
      6 the zoneinfo data files in /usr/share/lib/zoneinfo.  The zic command can be
      7 used with the zoneinfo source files to create additional data files.
      8 
      9 The zoneinfo files track the Olson public source provided at
     10 ftp://elsie.nci.nih.gov/pub/, therefore zoneinfo files may be added and
     11 removed as the Solaris source is updated.  The current Solaris release of
     12 the zoneinfo files is based on tzdata2009q.tar.gz.
     13 
     14 The /usr/share/lib/zoneinfo/GMT[+-]* timezones listed below have been
     15 removed from the release.  Replace usage of the
     16 /usr/share/lib/zoneinfo/GMT[+-]* files with the equivalent quoted timezone
     17 (see environ(5)).  Note the signs of the offsets of the equivalent quoted
     18 timezone are reversed from the signs of the /usr/share/lib/zoneinfo/GMT[+-]*
     19 files.
     20 
     21 For example, replace TZ=:GMT+1, with TZ="<GMT-1>-1".  (The colon (:) is
     22 significant.  Without the colon, for example TZ=GMT+1, an unquoted timezone
     23 is used;  unquoted timezones are not affected by the removal of the zoneinfo
     24 timezone files listed below.)
     25 
     26 The following files have been removed from the release:
     27 
     28 /usr/share/lib/zoneinfo/GMT-12
     29 /usr/share/lib/zoneinfo/GMT-11
     30 /usr/share/lib/zoneinfo/GMT-10
     31 /usr/share/lib/zoneinfo/GMT-9
     32 /usr/share/lib/zoneinfo/GMT-8
     33 /usr/share/lib/zoneinfo/GMT-7
     34 /usr/share/lib/zoneinfo/GMT-6
     35 /usr/share/lib/zoneinfo/GMT-5
     36 /usr/share/lib/zoneinfo/GMT-4
     37 /usr/share/lib/zoneinfo/GMT-3
     38 /usr/share/lib/zoneinfo/GMT-2
     39 /usr/share/lib/zoneinfo/GMT-1
     40 /usr/share/lib/zoneinfo/GMT+1
     41 /usr/share/lib/zoneinfo/GMT+2
     42 /usr/share/lib/zoneinfo/GMT+3
     43 /usr/share/lib/zoneinfo/GMT+4
     44 /usr/share/lib/zoneinfo/GMT+5
     45 /usr/share/lib/zoneinfo/GMT+6
     46 /usr/share/lib/zoneinfo/GMT+7
     47 /usr/share/lib/zoneinfo/GMT+8
     48 /usr/share/lib/zoneinfo/GMT+9
     49 /usr/share/lib/zoneinfo/GMT+10
     50 /usr/share/lib/zoneinfo/GMT+11
     51 /usr/share/lib/zoneinfo/GMT+12
     52 /usr/share/lib/zoneinfo/GMT+13
     53 
     54 As zoneinfo timezones are updated, the savings/daylight transition rules
     55 and timezone name abbreviations may change.  This can affect how 
     56 the times are calculated in the local timezone.  Therefore the interpretation
     57 of a time_t value can vary amongst Solaris releases that use different
     58 versions of the zoneinfo timezones.
     59 
     60 The zoneinfo timezone data files do not transition past
     61 Tue Jan 19 03:14:07 2038 GMT.  Therefore for 64-bit applications using
     62 zoneinfo timezones, calculations beyond this date may not use the correct
     63 offset from standard time, and could return incorrect values.  This affects
     64 64-bit versions of interfaces such as ascftime(3C), cftime(3C), ctime(3C),
     65 getdate(3C), ftime(3C), mktime(3C), and localtime(3C).

     67 For more information see zic(1M), zdump(1M), environ(5), TIMEZONE(4),
     68 ctime(3C), and mktime(3C) man pages.
