Warning

Please do not use any of the timezones listed here (besides UTC), they only exist for backward compatible reasons, and may expose erroneous behavior. Furthermore, these timezones may be removed from the IANA timezone database at any time.

Warning

If you disregard the above warning, please also note that the IANA timezone database that provides PHP's timezone support uses POSIX style signs, which results in the Etc/GMT+n and Etc/GMT-n time zones being reversed from common usage.

For example, the time zone 8 hours ahead of GMT that is used in China and Western Australia (among other places) is actually Etc/GMT-8 in this database, not Etc/GMT+8 as you would normally expect.

Once again, it is strongly recommended that you use the correct time zone for your location, such as Asia/Shanghai or Australia/Perth for the above examples.
