date_default_timezone_set — Sets the default timezone used by all date/time functions in a script
date_default_timezone_set() sets the default timezone used by all date/time functions.
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.
timezoneId
The timezone identifier, like UTC
,
Africa/Lagos
, Asia/Hong_Kong
, or
Europe/Lisbon
. The list of valid identifiers is
available in the Список підтримуваних часових поясів.
This function returns false
if the
timezoneId
isn't valid, or true
otherwise.
