The timezone identifier, like UTC, Africa/Lagos, Asia/Hong_Kong, or Europe/Lisbon. The list of valid identifiers is available in the elenco delle Timezone supportate.

Valori restituiti

This function returns false if the timezoneId isn't valid, or true otherwise.

Example #1 Getting the default timezone

<?php
date_default_timezone_set
('America/Los_Angeles');

$script_tz = date_default_timezone_get();

if (
strcmp($script_tz, ini_get('date.timezone'))){
echo
'Script timezone differs from ini-set timezone.';
} else {
echo
'Script timezone and ini-set timezone match.';
}
?>
