It returns the date minus one day. Maybe this error occures with other strings also. Test script: --------------- <?php $dt = new DateTime('-1999-06-22 00:00:00'); echo "\nThis should be -1999-06-22 00:00:00 -> " . $dt->format('Y-m-d H:i:s'); $dt = new DateTime('-1916-06-22 00:00:00'); echo "\nThis should be -1916-06-22 00:00:00 -> " . $dt->format('Y-m-d H:i:s'); Expected result: ---------------- This should be -1999-06-22 00:00:00 -> -1999-06-22 00:00:00 This should be -1916-06-22 00:00:00 -> -1916-06-22 00:00:00 Actual result: -------------- This should be -1999-06-22 00:00:00 -> -1999-06-22 00:00:00 This should be -1916-06-22 00:00:00 -> -1916-06-21 00:00:00 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=73294&edit=1
