date_default_timezone_set
(PHP 5 >= 5.1.0)
date_default_timezone_set —
Sets the default timezone used by all date/time functions in a script
Description
bool date_default_timezone_set
( string $timezone_identifier
)
Note:
Since PHP 5.1.0 (when the date/time functions were rewritten), every call
to a date/time function will generate a E_NOTICE if
the timezone isn't valid, and/or a E_STRICT message
if using the system settings or the TZ environment
variable.
Instead of using this function to set the default timezone in your script,
you can also use the INI setting date.timezone to set the default
timezone.
Parameters
-
timezone_identifier
-
The timezone identifier, like UTC or
Europe/Lisbon. The list of valid identifiers is
available in the List of Supported Timezones.
Return Values
This function returns FALSE if the
timezone_identifier
isn't valid, or TRUE
otherwise.
