Description:
------------
I run such script on my webserver Apache 2.0 running PHP 5.1.6
Before the date 28 October 2006 inclusive, everything works fine. On the 29 October, the result does not yield string "29 October 2006" and after 29 October 2006 the script simply crashes the server (the task manager indicates 50% CPU time on apache.exe from my pentium 4 HT processor for 30 seconds before timeout)

Halloween Egg? (not easter egg)?

Reproduce code:
---------------
$now = mktime(0,0,0,date('m'),date('d'),date('Y'));
$first = mktime(0,0,0,10,1,2006);
$diff = ($now - $first)/86400 + 1;
for ($i=$diff;$i>0;$i--) {
	$a = strtotime("-$i day");
	$today = getdate("$a");
	$month_format = $today['mon'];
	$day_format = $today['mday'];
	$year_format = $today['year'];
	echo "$month_format/$day_format/$year_format<br />";
}

Expected result:
----------------
Anything ranging from the date 9/30/2006 up to the current date set on the server clock

Actual result:
--------------
//date:27 october 2006 (correct)
...
10/25/2006
10/26/2006
10/27/2006

//date:28 october 2006 (correct)
...
10/25/2006
10/26/2006
10/27/2006
10/28/2006

//date:29 october 2006 (simply '10/29/2006' missing)
...
10/25/2006
10/26/2006
10/27/2006
10/28/2006

//date:30 october 2006 and so on (simply crashes the system and returns...
"Fatal error: Maximum execution time of 30 seconds exceeded in D:\php\toko\ntz.php on line 15")
