Description:
------------
$arrivalDate = "2008-03-29";
$departureDate = "2008-04-02";

$diff = get_time_difference($arrivalDate, $departureDate);

echo $diff['days'];   (result is: 3)

that's wrong, 'cause it must be 4. (30, 31, 1, 2)

I notice that 31 march 2008 (isn't reconized)

I thought it was caused by 29 february, but in 2004, 2000 and 2012 it's working fine.



Reproduce code:
---------------
$arrivalDate = "2008-03-29";
$departureDate = "2008-04-02";

$diff = get_time_difference($arrivalDate, $departureDate);

echo $diff['days']; 

Expected result:
----------------
$diff => must be 4, and not 3

Actual result:
--------------
3
