[Zope] how to import strptime.py to ZOPE WIN installation?

Hi, I want to do some form typechecking on the server side for date input. Strptime() is what I need, but the function is not part of the windows distribution. So I was happy to discover strptime.py from Andy Eskilsson (http://www.fukt.hk-r.se/~flognat), which works nicely from the commandline in PythonWin. But how the hell (sorry) can I get it "into" my Python/ZOPE installation? I´d like to call it from a Python script. Reading lots of list archives and the like didn´t give me a clue yet. Please help! Hope I am not off topic (is this a Python thing?), but others might be interested in strptime.py functionality as well. thanks, -georg-
