Description:
------------
strtotime calls with a timezone embedded function correctly but continually use up 
memory. In a daemon program this becomes quickly fatal.


Test script:
---------------
<?php
while (true) {
    strtotime('Monday 00:00 Europe/Paris');    // Memory leak
}
?>

<?php
while (true) {
    date_default_timezone_set("Europe/Paris");
    strtotime('Monday 00:00');    // No memory leak
}
?>

Expected result:
----------------
Memory usage should remain stable.
