Description:
------------
When using strtotime() in PHP 5.1.4, it returns an inaccurate timestamp, but PHP 5.0.4 and 4.4.2 return the correct timestamp.

Reproduce code:
---------------
php -r 'echo date("r", strtotime("Mon, 08 May 2006 13:06:44 -0400 +30 days"));'

Expected result:
----------------
Wed, 07 Jun 2006 13:06:44 -0400

Actual result:
--------------
Mon, 12 Jun 2006 13:06:44 -0400

I'm not sure whether this is related, but I found a new issue with strtotime(). It looks like the words "second" and "third" are not working correctly. 

Reproduce code:
echo date('r', strtotime('May 1st first Monday')) . "\n";
echo date('r', strtotime('May 1st second Monday')) . "\n";
echo date('r', strtotime('May 1st third Monday')) . "\n";
echo date('r', strtotime('May 1st fourth Monday')) . "\n";
echo date('r', strtotime('May 1st fifth Monday')) . "\n";

I expect the output to be:

Mon, 08 May 2006 00:00:00 -0400
Wed, 15 May 2006 00:00:00 -0400
Wed, 22 May 2006 00:00:00 -0400
Mon, 29 May 2006 00:00:00 -0400
Mon, 05 Jun 2006 00:00:00 -0400

but the actual output (with PHP 5.1.4) is:

Mon, 08 May 2006 00:00:00 -0400
Wed, 31 Dec 1969 19:00:00 -0500
Wed, 31 Dec 1969 19:00:00 -0500
Mon, 29 May 2006 00:00:00 -0400
Mon, 05 Jun 2006 00:00:00 -0400

With PHP 4.4.2, the actual output is:

Tue, 01 May 2001 00:00:00 -0400
Mon, 01 May 2006 00:00:01 -0400
Thu, 01 May 2003 00:00:00 -0400
Sat, 01 May 2004 00:00:00 -0400
Sun, 01 May 2005 00:00:00 -0400

Actually, I meant that I expect the output to be (Wed should be changed to Mon):

Mon, 08 May 2006 00:00:00 -0400
Mon, 15 May 2006 00:00:00 -0400
Mon, 22 May 2006 00:00:00 -0400
Mon, 29 May 2006 00:00:00 -0400
Mon, 05 Jun 2006 00:00:00 -0400

strtotime("May 1st third Monday") returns false in the latest CVS and I think the result is correct, since the date is invalid.
