Description:
------------
Incorrect second argument in touch() on winter/summer time

Reproduce code:
---------------
go1.php
<?
  	echo "Current winter-time (Moscow +3 GTM): ".date("r (T)")." ".phpversion()."\r\n";

	touch("1.txt", mktime(3,0,0,6,1,2008));
    clearstatcache();
  	$t1=filemtime("1.txt");
  	echo "file1: ".date("d/m/Y H:i:s",$t1)." (must be 3:00)\r\n";

	touch("2.txt", mktime(12,0,0,1,2,2009));
    clearstatcache();
  	$t2=filemtime("2.txt");
  	echo "file2: ".date("d/m/Y H:i:s",$t2)." (must be 12:00)\r\n";
?>



go2.php
<?
  	echo "Current winter-time (Moscow +3 GTM): ".date("r (T)")." ".phpversion()."\r\n";
	touch("1.txt", mktime(mt_rand(0,23),mt_rand(0,59),0,6,1,2008,mt_rand(0,1)));
    copy("1.txt", "2.txt");
    clearstatcache();
  	$t1=filemtime("1.txt");
	touch("2.txt", $t1);
    clearstatcache();
  	$t2=filemtime("2.txt");
  	echo "file1: ".date("d/m/Y H:i:s",$t1)."\r\n";
  	echo "file2: ".date("d/m/Y H:i:s",$t2)." (file1 must be equal file2)\r\n";
?>

file1: 01/06/2008 03:00:00 (must be 3:00)
file2: 02/01/2009 12:00:00 (must be 12:00)

file1: 01/06/2008 03:00:00 (must be 3:00)
file2: 02/01/2009 12:00:00 (must be 12:00)

---------------------------------------------------

Command `dir 1.txt`:
01.06.2008  03:00                 0 1.txt

---------------------------------------------------
Windows XP, PHP 5.1.6, go2.php

Current winter-time (Moscow +3 GTM): Wed, 21 Jan 2009 11:23:15 +0300 (MSK) 5.2.8
file1: 01/06/2008 18:26:00
file2: 01/06/2008 19:26:00 (file1 must be equal file2)



Actual result:
--------------
go1.php
file1: 01/06/2008 03:00:00 (must be 3:00)

go2.php
filemtime(1.txt) must be equal filemtime(2.txt), after copy(1.txt, 2.txt). 

Shell command "copy 1.txt 2.txt" is correct. And in PHP 4.x/3.x all ok. I need downgrade? .-)
