 New Comment:

proposed solution:
->add and ->sub methods should internally convert to UTC before add or
sub the interval, then should re-set the original timezone

Description:
------------
hi
when dateinterval walks across a dst change 

$a = DateTime::createFromFormat
(
"d/m/Y H:i:s e",
"03/03/2011 01:38:25 europe/rome"
);

$a = $a->add(new DateInterval("P1M")); // now we have DST in italy

should add +1 hour too, I think, but it doesn't

thank you
