<?php $time ='2013-03-30 01:15:00'; $stamp = strtotime($time); for($i=0; $i<4; $i++){ echo date('Y-m-d H:i:s', strtotime("+{$i} hours", $stamp))."<br />\n"; }

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
