Description:
------------
Hi,

Mktime returns bad value when we worl on marchs date.
The diffrence bettween dates is wrong.

Test script:
---------------
<?

$du ="26/03/2011";
$au ="28/03/2011";

$duArr = explode("/", $du);
$auArr = explode("/", $au);

$hour = 0;//date("H");
		$minute = 0;//date("i");
		$second = 0;//date("s");
		$date1 = mktime($hour,$minute,$second,intval($duArr[1]),intval($duArr[0]),intval($duArr[2]));
		$date2 = mktime($hour,$minute,$second,intval($auArr[1]),intval($auArr[0]),intval($auArr[2]));

$diffDate = $date2 - $date1;
		$diffJours = floor($diffDate/(60*60*24));


echo $diffJours."<br>";

?>

Expected result:
----------------
Must return 2



Actual result:
--------------
Returning 1

We are happy to tell you that you just discovered Daylight Savings
Time. For more information see:

Instead of using mktime/date consider using gmmktime and gmdate which do
not suffer from DST.
