Description:
------------
I quote from Bug #40568:

PHP filemtime/fileatime/filectime (and maybe stat itself) functions
should use GetFileTime() Win32API (or GetFileAttributesEx()), not stat() to retrieve the actual times from files. Otherwise the returned time is shifted by one hour in some conditions.

This (mis)behaviour is actually DOCUMENTED by Microsoft, so it does not qualify for "bogus - fix microsoft libraries" bug rejection -- Microsoft already fixed their documentation and even indicated that "This behavior is by design."

Reproduce code:
---------------
<?php
  $fullfilename='test.dll';
  $ft=filemtime($fullfilename);
  touch($fullfilename.'.md5',$ft);
  $nt=filemtime($fullfilename.'.md5');
  echo $ft.' : '.$nt;
?>

Please get test.dll from http://www.vezz.it/php/test.zip

Original file modification date:
19 feb 2008, 19.08.47

Expected result:
----------------
filemtime should return the same result for the two files.

1203440927 : 1203440927 



Actual result:
--------------
1203440927 : 1203437327

The touched file date is one hour back.
19 feb 2008, 18.08.47 instead of 19 feb 2008, 19.08.47
