Bug description:Having a bug when using date_diff($t1,$t2)

Description:
------------
Hi,
Sorry if not posting this bug in the correct section. I'm currently having
a bug when using date_diff().
Seems that when the "day" part of the dates is the same on both dates
compared, the function returns "0 Days" instead of 30 or some Days.

Test script:
---------------
$datetime1 = date_create('2010-03-08');
$datetime2 = date_create('2010-04-08');
$interval = date_diff($datetime1,$datetime2);
echo $interval;
//=> returns "+0 Days"
//
//Whereas
//
$datetime1 = date_create('2010-03-08');
$datetime2 = date_create('2010-04-07');
$interval = date_diff($datetime1,$datetime2);
echo $interval;
//Will return "+30 Days"

Expected result:
----------------
Should return "a whole month" interval like +31 Days in that particular
case.

Actual result:
--------------
returns +0 Days
