title: php strtotime return wrong timestamp
body: <p>I'm using php strtotime function 
  (date format <code>Day, month and two digit year, with dots or tabs</code> d.m.y from doc: <a href="http://www.php.net/manual/en/datetime.formats.date.php" rel="nofollow">http://www.php.net/manual/en/datetime.formats.date.php</a>) 
  and found problem:</p>
  
  <p>From php.net example strtotime("30.6.08") -> 1214773200 -> Sun, 29 Jun 2008 21:00:00 GMT(reverse convert right)</p>
  
  <p>another variant strtotime("24.10.13") -> 1381180213 -> Mon, 07 Oct 2013 21:10:13 GMT (reverse is not right)</p>
  
  <p>but strtotime("30.10.13") -> 1383084000 -> Tue, 29 Oct 2013 22:00:00 GMT (reverse result again correctly)</p>
