You don't want the python-dev list for this type of question.
Python-dev is for development *of* Python. For usage questions such as
this, you would be better asking on python-list (or, equivalently, the
Usenet group comp.lang.python).

To assist with your question, though, I'd suggest you look at the
documentation of the datetime module, which allows you to do what you
are after (and much more).
