Can't reproduce with both 4.4 and 5.2.
I get 17 and 16, both are correct results.
Also, please try to be more clear when you provide reproduce code. Lot
of HTML and text do not add any understanding.

Description:
------------
strtotime starts generating wrong timestamps in November, 2007. Only
wrong in the month of November. Rest of months are ok.
strtotime("3 Friday", $november_2006_timestamp) generates correct
timestamp with date which is the 3rd Friday in November 2006.
strtotime("3 Friday", $november_2007_timestamp) generates wrong
timestamp with date which should be the 3rd Friday in November 2007.
The date generated is -1 day, in this case, Thursday in the month of
November, 2007.
All dates generated are wrong in the months of November. Tested up to
2009. Every other month works ok.
Reproduce code:
---------------
<?php
$month11_2006_timestamp = mktime(0,0,0,11,1,2006);
$month11_2006_day_timestamp = strtotime("3
Friday",$month11_2006_timestamp);
$month11_2006_date = date('j',$month11_2006_day_timestamp);
echo"<h1>month11_2006_date for Friday 2006 = $month11_2006_date
(correct)</h1>";
echo"<h1>This correctly shows the 3rd Friday date for November, 2006
</h1>";
//test of strtotime() generating date string for day in 3 week in
November 2007
$month11_2007_timestamp = mktime(0,0,0,11,1,2007);
$month11_2007_day_timestamp = strtotime("3
Friday",$month11_2007_timestamp);
$month11_2007_date = date('j',$month11_2007_day_timestamp);
echo"<h1>month11_2007_date = $month11_2007_date (wrong)</h1>";
echo"<h1>This incorrectly shows the 3rd Friday date for November, 2007
<br>as the 15th of November 2007 which is a Thursday.
<p>Every day-date generated from November 2007-2009 produces at -1
day from the standard.
So other days are also wrong. It is always November. The other
months work fine.</p></h1>";
Expected result:
----------------
month11_2006_date for Friday 2006 = 17 (correct)
This correctly shows the 3rd Friday date for November, 2006
month11_2007_date = 15 (wrong)
This incorrectly shows the 3rd Friday date for November, 2007
as the 15th of November 2007 which is a Thursday.
Every day-date generated from November 2007-2009 produces at -1 day
from the standard. So other days are also wrong. It is always November.
The other months work fine.
