As far as I can see, it's always the current time + 1 day. Test script: --------------- <?php echo PHP_VERSION . "\r\n"; $datetime1 = new DateTime('now'); echo $datetime1->format('Y-m-d H:i:s') . "\r\n"; $datetime2 = new DateTime('first day of this month'); echo $datetime2->format('Y-m-d H:i:s') . "\r\n"; $datetime3 = new DateTime('first day'); echo $datetime3->format('Y-m-d H:i:s') . "\r\n"; Expected result: ---------------- 2013-09-30: 5.5.4 2013-09-30 07:59:29 2013-09-01 07:59:29 2013-09-01 07:59:29 2013-10-01: 5.5.4 2013-10-01 07:59:29 2013-10-01 07:59:29 2013-10-01 07:59:29 2013-10-02: 5.5.4 2013-10-02 07:59:29 2013-10-01 07:59:29 2013-10-01 07:59:29 Actual result: -------------- 2013-09-30: 5.5.4 2013-09-30 07:59:29 2013-09-01 07:59:29 2013-10-01 07:59:29 2013-10-01: 5.5.4 2013-10-01 07:59:29 2013-10-01 07:59:29 2013-10-02 07:59:29 2013-10-02: 5.5.4 2013-10-02 07:59:29 2013-10-01 07:59:29 2013-10-03 07:59:29 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=65807&edit=1
