From a brief reading of the source code, dateTime->add() doesn't
*appear* use the underlying strtotime library, so I don't see why this
function should be forced to have the same weakness of that function.
IMO, these date functions would be far more useful if they adhere to
common date manipulation ideals instead of using simple math as they are
currently doing.
As it stands now, the dateTime->add() function cannot be relied upon
for any sort of accounting math and IMO completely defeats the purpose
of specialized dateTime functions.

Description:
------------
dateTime->add(dateInterval) isn't applying proper calendar math when
adding intervals.
Reproduce code:
---------------
$dateTest = new dateTime('2008-01-31',new dateTimeZone("GMT"));
print_r($dateTest);
$dateTest->add(new dateInterval('P1M'));
print_r($dateTest);
Expected result:
----------------
DateTime Object
(
[date] => 2008-01-31 00:00:00
[timezone_type] => 3
[timezone] => UTC
)
DateTime Object
(
[date] => 2008-02-28 00:00:00
[timezone_type] => 3
[timezone] => UTC
)
Actual result:
--------------
DateTime Object
(
[date] => 2008-01-31 00:00:00
[timezone_type] => 3
[timezone] => UTC
)
DateTime Object
(
[date] => 2008-03-02 00:00:00
[timezone_type] => 3
[timezone] => UTC
)
