( I am sorry to whomever wrote this, I didn't keep the source where I found it ) function convert_time_zone($date_time, $from_tz = 'UTC', $to_tz = 'America/Toronto') { $time_object = new DateTime($date_time, new DateTimeZone($from_tz)); $time_object->setTimezone(new DateTimeZone($to_tz)); return $time_object->format('Y-m-d H:i:s'); } Maybe this can help you?
