I found this function a while back when I was converting UTC to EST... simple task I know, but still...

( 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?
