Description:
------------
Touch appears to always apply a timestamp that is exactly one-hour earlier then the given timestamp, in Windows. It appears to work fine in PHP 5.0.4 and 4.1.2 in Linux.

Reproduce code:
---------------
touch('b', 0);

var_dump(stat('b'));

Expected result:
----------------
array(26) {
  [0]=>
  int(2)
  [1]=>
  int(0)
  [2]=>
  int(33206)
  [3]=>
  int(1)
  [4]=>
  int(0)
  [5]=>
  int(0)
  [6]=>
  int(2)
  [7]=>
  int(0)
  [8]=>
  int(-3600)
  [9]=>
  int(-3600)
  [10]=>
  int(1182374129)
  [11]=>
  int(-1)
  [12]=>
  int(-1)
  ["dev"]=>
  int(2)
  ["ino"]=>
  int(0)
  ["mode"]=>
  int(33206)
  ["nlink"]=>
  int(1)
  ["uid"]=>
  int(0)
  ["gid"]=>
  int(0)
  ["rdev"]=>
  int(2)
  ["size"]=>
  int(0)
  ["atime"]=>
  int(0)
  ["mtime"]=>
  int(0)
  ["ctime"]=>
  int(1182374129)
  ["blksize"]=>
  int(-1)
  ["blocks"]=>
  int(-1)
}

Actual result:
--------------
// mtime and ctime are -3600.

array(26) {
  [0]=>
  int(2)
  [1]=>
  int(0)
  [2]=>
  int(33206)

}

What does this output for you:

<?php

echo time(), "\n";
touch('b'); // 2nd parameter is optional..
$b = stat('b');
echo $b['ctime'], "\n";

?>

ctime doesn't appear to be afflicted.

Actually I think it's just the thing that you pass '0' to touch() as 2nd parameter..
 [2007-06-20 22:27 UTC] aeolianmeson at blitzeclipse dot com 
It's just easier to see when I use (0). I was using normal timestamps before.

Plus, this only happens with Windows.

Of course. What is your system timezone set to? And what about the timezone setting in php.ini, date.timezone ?
 [2007-06-21 13:33 UTC] aeolianmeson at blitzeclipse dot com 
Timezone is set to -5 at runtime. OS is setting to Detroit (-5)... But, timezones don't matter until epoch times are converted to strings-- This wouldn't apply since we're just talking about the timestamps.
 [2007-06-21 13:37 UTC] sniper@php.net 
Yes, that's how it should work but maybe not. What is date.timezone set for you?
 [2007-06-21 13:38 UTC] aeolianmeson at blitzeclipse dot com 
It's set to 'America/Detroit' at runtime, which is still -5 (or -4 during DST).
