Description:
------------
http://bugs.php.net/bug.php?id=41334 -- DateTime serialization was added in PHP 5.3, but DateTimeZone still serializes to an empty object, it's serialized string is always:

O:12:"DateTimeZone":0:{}

Test script:
---------------
<?
$x = new DateTimeZone('Australia/Victoria');
echo $x->getName()."\n";
$x = serialize($x);
$x = unserialize($x);
echo $x->getName()."\n";
?>


Expected result:
----------------
Australia/Victoria
Australia/Victoria

Actual result:
--------------
Australia/Victoria
