Description:
------------
You can create an invalid DateTime object by giving it a string in the GNU Date Input Format syntax. 

For instance, '2006-04-02 02:05:00 America/New_York' is supposed to be invalid because DST takes effect on that day, such that all times >= 02:00:00 and < 03:00:00 are supposed to be invalid. Trying to create a DateTime object with that string is supposed to return FALSE.

The bug is probably not caused by an outdated timezone database because the timezone database in use is version 2006.14.

I could not test for the bug in the latest snapshot because the latest snapshot crashes Apache2 on my machine( and that's a different story).

Reproduce code:
---------------
<?
$foo = date_create('2006-04-02 02:05:00 America/New_York');
if($foo)
{
  echo $foo->format('Y-m-d H:i:s e'),$foo->format('I')?' DST':'';
}
else
{
  echo "FALSE";
}
?>

Expected result:
----------------
FALSE

Actual result:
--------------
2006-04-02 02:05:00 America/New_York DST
