date_default_timezone_set
Sets the default timezone used by all date/time functions in a script
(PHP 5 >= 5.1.0)
bool date_default_timezone_set ( string timezone_identifier )
date_default_timezone_set() sets the default timezone used by all date/time functions.
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
UTCorEurope/Lisbon. The list of valid identifiers is available in the Appendix J, List of Supported Timezones.
Return Values
This function returns FALSE if the
timezone_identifier isn't valid, or TRUE
otherwise.
