Maybe from your POV, but from our POV the only way we can get time to work
on Python is talk all of you into doing Zope work for Jim <wink>.

I believe all /F is asking for is that all datetime types supply two
specific methods, so that he can get the year etc out of anybody's datetime
object via a uniform spelling. It's a fine idea.

If /F is asking more than that datetime types implement a specific
interface, he's got some major rewriting to do <wink>. Python doesn't have
a good way to spell "interface" now, so think of it as a do-nothing base
class, inheriting from which means absolutely nothing except that (a) you
promise to supply the methods /F specified, and (b) /F can use isinstance to
determine whether or not a given object supports this interface.

That's getting back to what Jim wants. Maybe someone should ask him what
that is <wink>.
