+The /usr/share/lib/zoneinfo/src directory contains zoneinfo timezone source
+files.  These source files have been compiled using zic(1M) to create
+the zoneinfo data files in /usr/share/lib/zoneinfo.  The zic command can be
+used with the zoneinfo source files to create additional data files.
+
+The zoneinfo files track the Olson public source provided at
+ftp://elsie.nci.nih.gov/pub/, therefore zoneinfo files may be added and
+removed as the Solaris source is updated.  The current Solaris release of
+the zoneinfo files is based on tzdata2011h.tar.gz.
+
+The /usr/share/lib/zoneinfo/GMT[+-]* timezones listed below have been
+removed from the release.  Replace usage of the
+/usr/share/lib/zoneinfo/GMT[+-]* files with the equivalent quoted timezone
+(see environ(5)).  Note the signs of the offsets of the equivalent quoted
+timezone are reversed from the signs of the /usr/share/lib/zoneinfo/GMT[+-]*
+files.
+
+For example, replace TZ=:GMT+1, with TZ="<GMT-1>-1".  (The colon (:) is
+significant.  Without the colon, for example TZ=GMT+1, an unquoted timezone
+is used;  unquoted timezones are not affected by the removal of the zoneinfo
+timezone files listed below.)
+
+The following files have been removed from the release:
+
+/usr/share/lib/zoneinfo/GMT-12
+/usr/share/lib/zoneinfo/GMT-11
+/usr/share/lib/zoneinfo/GMT-10
+/usr/share/lib/zoneinfo/GMT-9

+/usr/share/lib/zoneinfo/GMT+13
+
+As zoneinfo timezones are updated, the savings/daylight transition rules
+and timezone name abbreviations may change.  This can affect how 
+the times are calculated in the local timezone.  Therefore the interpretation
+of a time_t value can vary amongst Solaris releases that use different
+versions of the zoneinfo timezones.

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