Huh? What's been a bubear? We're talking about using year=0, month=0, and
day=0 to mean that we don't care about the date. This is a bad idea.
I've never heard of anyone wanting to do this with Zope 2's DateTime.

Do you realize that we're talking about time of day, not date-time.
If I have a value like "4:30" without a date, why would math be essential?

It didn't really mean much of anything other than that I didn't want
Marius to be put off by the emphatic "no".
