Now is about 20010506T073000+0530 localtime, which is 20010506T020000Z.
Or, if you want millisecond precision, 20010506T073000.000+0530.
This representation is (as far as I can see; please tell me if I am
missing something) ISO 8601 compliant, and backwards compatible with
ICal except for fractional seconds and offset timezones, both of which
are optional. I've also almost finished a parser for it.
I was going to write Date::ISO, but I see you already did. :-)

Exactly, which means that you can give new() any object which knows how
to date itself:
$time = $obj;
if (ref $obj) {
if ($obj->can('foo')) { $time = $obj->foo; }
else { croak "Your object doesn't know how to foo."; }
}
$self->_parse($time);
