I ported a small piece of code from the CVS sources into a python module
that returns the number of seconds since the Epoch instead of a tuple. I
called it 'getdate', and released it a while ago to my startship.python.net
the module is comprised of one function that is able to act intelligently
when given various date formats like the ones you are describing and seems
to make the 'right' choice 'most' of the time. please try it out-- it might
suit your purposes nicely, especially if you are writing an interactive
application that accepts date input from a human user.
here is an example of this module in action:
