If the object is created by timestamp it works. Test script: --------------- <?php $dt = new DateTime('first day of this month'); // correct output: "2011-04-01 22:41:17" var_dump($dt); // wrong output: "2011-04-01 22:41:17" var_dump($dt->sub(new DateInterval('P2D'))); // correct output: "2011-03-30 20:41:17" var_dump(date_create('@' . $dt->getTimestamp())->sub(new DateInterval('P2D'))); ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=54579&edit=1
