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://ftp.iana.org/tz/releases/, 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 tzdata2016j.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:
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.
