Yep. Manual at http://hu1.php.net/manual/en/datetime.construct.php says:
"If an invalid date is specified, then an exception is now thrown. Previously
an
error was emitted."

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
PHP's date time handling auto-corrects wrong date/time values. This is similar
to doing:
class DateTime#1 (3) {
public $date =>
string(19) "2013-05-01 00:00:00"
public $timezone_type =>
int(3)
public $timezone =>
string(13) "Europe/London"
}
