Bug description: Sttotime returning wrong dates
Description:
------------
When converting weeks and days to a date using strtotime, some months
return the wrong dates. For instance, strtotime("first thursday",
mktime(0,0,0,11,1,2009)) returns 11/4/2009, which is a wednesday. There are
also issues using "last".
This seems to be happening with November 2009. I am not sure about other
years or other months. I think I had issues there as well, but
infrequently. I tried seeing if the issue is with any month when the first
day of the month is sunday, but it does not appear to be the case.
I am creating a new function to handle strtotime in this manner, because I
found more issues with using this function and creating a series of dates
that are incremented by a year.
Reproduce code:
---------------
public function getDateFromWeekAndDayOfMonth($d, $m, $y){
$fistDayOfMonth = mktime(0, 0, 0, $m, 1, $y)
$firstWeekForDay = strtotime("first " . $d, $fistDayOfMonth);
return $firstWeekForDay;
}
Expected result:
----------------
For the First Thursday in November 1, 2009, I expect to have the datetime
for 11-5-2009.
Actual result:
--------------
11-4-2009
