Have you looked at mx.DateTime:
http://www.egenix.com/products/python/mxBase/mxDateTime/

In matplotlib, I also use their Dates modules functions for
conversions (see the near bottom of the page):
http://matplotlib.sourceforge.net/matplotlib.dates.html

In the scipy sandbox, you can also build a package called
'TimeSeries':
http://www.scipy.org/SciPyPackages/TimeSeries

I also have trouble with date/times with whats available. Off the top
of my head... converting a numpy array of epochs to some datetime
object and back.

If I had the time I'd contribute additional functionality to Pierre's
and Matt's TimeSeries module (the one in scipy).
