Answer by safarov
Time left for new confirmation code:
$request_date = '2012-03-24 13:03:17';
$please_wait = '30 minutes';
$future_time = strtotime("+" . $please_wait, strtotime($request_date));
$time_left = $future_time - time(); //seconds left
Answer by Starx
Calculate the requested timestamp and sustract with currect time stamp
Solution:
$future = strtotime($request_date)+1800; // 1800 is 30 minutes
echo date("i", $future-time()); //this is the remaining minutes
