I don't have any complains about it.  There's a chance that DateTime might
cause confusion with Date:: and Time::, which would be a disadvantage.

My only other suggested namespace would be "Horology::" which could be
vague, but still conveys the purpose of the modules.

For one thing, using an entirely seperate namespace would help to
completely disassociate these modules from everything else in Date:: or
Time::.  Otherwise, we end up making the problem worse by making people
wonder if the modules created by this project are somehow compatable with
what is already out there.

Why not just a DateTime object, like we already have a CGI object?

Can you elaborate more on your preference towards Date::ICal?  Are you
saying that you have a preference towards the ISO 8601 time representation
(ie. "20030109T1808") for the internal data structure of the date/time

You wrote a lot, which is good.  I just wanted to comment on the Namespace
stuff and the base class.
