The zoneinfo timezones in the following left column may no longer be supported in a future release. These files may be removed from /usr/share/lib/zoneinfo. Replace usage of the zoneinfo timezones in the left column with the equivalent timezones in the right column.
When setting the TZ environment variable to a zoneinfo GMT[+-]* timezone, the timezone must be preceded with a colon (':') character. For example, replace the zoneinfo timezone setting TZ=:GMT+1, which is 1 hour east of the Prime Meridian, with the equivalent zoneinfo timezone setting TZ=:Etc/GMT-1.
The planned removal of the zoneinfo GMT[+-]* timezones does not affect POSIX-style GMT[+-]* timezone settings, for example TZ=GMT+1 (without the colon character). An equivalent zoneinfo timezone, located under /usr/share/lib/zoneinfo/Etc and with the same name, may be used instead. The POSIX-style timezone only displays the string "GMT" in the abbreviated timezone name, while the zoneinfo timezone displays the offset from GMT. For example, replace the POSIX-style timezone setting, TZ=GMT+1, with the equivalent zoneinfo timezone setting TZ=:Etc/GMT+1.
See environ.5 and zoneinfo.4 for more information.
