Bug description: strtotime() generates wrong date for 11th month 2007 on.
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.
