date_diff fixes status

Hi!

What is the status of fixing date module with regard to TLA timezones
handling - this code still fails:

<?php
$t = new DateTime('2010-11-06 18:38:28 EDT'); // prev, zt2
$ts = $t->format('U');
var_dump($ts);
$t->setTimestamp($ts);
var_dump($t);

and also many tests are in XFAIL. Is there any chance we can get this
fixed for 5.4?
