Description:
------------
We found that createFromFormat work incorrect.
If we use reset in format ("!") and don't send year then we will receive new date 
in 1970 year, php don't change day of week ("Wed"), it change day("05").

It work correct in 5.3.8

Maybe you broke this when fix this:

Test script:
---------------
<?php
$str = "6:15 pm Wed, Oct 5";
$date = DateTime::createFromFormat("!g:i a D, M d", $str);
var_dump($date);

Expected result:
----------------
class DateTime#1 (3) {
  public $date =>
  string(19) "1970-10-05 18:15:00"
  public $timezone_type =>
  int(3)
  public $timezone =>
  string(13) "Europe/Berlin"
}

(php 5.3.8)

Actual result:
--------------
object(DateTime)#1 (3) {
  ["date"]=>
  string(19) "1970-10-07 18:15:00"
  ["timezone_type"]=>
  int(3)
  ["timezone"]=>
  string(15) "Europe/Helsinki"
}
