Description:
------------
The section states that "Emits Exception in case of an error." but fails to mention that this behavior only applies to PHP 5 >= 5.3.0.
If 5.2, DateTime::__construct triggers an error, not an exception.

Test script:
---------------
<?php

set_error_handler('dummy');

try {
        $date = new DateTime('not a date');
}
catch (Exception $e) {
        die("\ncaught exception");
}

die("\ndying");

function dummy() {
        echo "\ndummy function";
}
?>



Expected result:
----------------
"caught exception"

Actual result:
--------------
"dummy"
