Bug description:Date::diff keeps subtracting after Date::sub
Description:
------------
After executing a sub() on a DateTime object, for every call of diff(),
both DateTime objects start getting subtracted by the value that was passed
on sub().
Test script:
---------------
date_default_timezone_set('GMT');
$t1 = new DateTime('2010-01-01 00:00:00');
$t2 = new DateTime('2010-01-01 00:00:00');
$dif = new DateInterval('P1D');
$t2->sub($dif);
$t1->sub($dif);
for ($x = 0; $x < 3; $x++) {
$t1->diff($t2);
echo $t1->format("r\n");
echo $t2->format("r\n");
echo "\n";
}
Expected result:
----------------
Fri, 01 Jan 2010 00:00:00 +0000
Fri, 01 Jan 2010 00:00:00 +0000
Fri, 01 Jan 2010 00:00:00 +0000
