Each time DateTime::getTimestamp is called, a previously called
DateTime::sub value is applied. This does not occur with DateTime::add.
Reproduce code:
---------------
$work_time = new DateTime("2010-01-30 12:00:00");
$work_time->sub(new DateInterval("P7D"));
$window_start = $work_time->getTimestamp();
echo date("Y-m-d H:i:s", $window_start) . "<br />";
$window_start = $work_time->getTimestamp();
echo date("Y-m-d H:i:s", $window_start) . "<br />";
Expected result:
----------------
2010-01-23 12:00:00
2010-01-23 12:00:00
Actual result:
--------------
2010-01-16 12:00:00
2010-01-09 12:00:00
