date_default_timezone_set
Sets the default timezone used by all date/time functions in a script
&reftitle.description;
booldate_default_timezone_setstringtimezoneIDdate_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_WARNING 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.
&reftitle.parameters;
timezoneID
The timezone identifier, like UTC,
Africa/Lagos, Asia/Hong_Kong, or
Europe/Lisbon. The list of valid identifiers is
available in the .
&reftitle.returnvalues;
This function returns &false; if the
timezoneID isn't valid, or &true;
otherwise.
