Fix forthcoming. ------------------------------------------------------------------------ [2011-03-22 00:29:12] 1cdecoder at gmail dot com Description: ------------ DateTime::add() method bug Test script: --------------- $date = new DateTime('first day of this month'); echo $date->format('Y-m-d H:i:sP'); $date->add(new DateInterval('P1D')); echo $date->format('Y-m-d H:i:sP'); Expected result: ---------------- 2011-03-01 01:17:31+02:00 2011-03-02 01:17:31+02:00 Actual result: -------------- 2011-03-01 01:17:31+02:00 2011-03-01 01:17:31+02:00 ================= ====== BUT ====== ================= $date = new DateTime('first day of this month'); echo $date->format('Y-m-d H:i:sP'); $date->add(new DateInterval('P1M')); echo $date->format('Y-m-d H:i:sP'); Expected result: ---------------- 2011-03-01 01:17:31+02:00 2011-04-01 01:17:31+02:00 Actual result: -------------- 2011-03-01 01:17:31+02:00 2011-04-01 01:17:31+02:00 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=54340&edit=1
