Since the datetime module turned out to be mostly a reimplementation
of mxDateTime, why not continue down that road ?
http://www.egenix.com/products/python/mxBase/mxDateTime/
Let's see:
>>> from mx.DateTime import *
>>> DateTime(2008,11,15).ticks()
1226703600.0
>>> TimeDelta(seconds=100)
<mx.DateTime.DateTimeDelta object for '00:01:40.00' at 837030>
>>> TimeDelta(seconds=100) / TimeDelta(seconds=50)
2.0
>>> TimeDelta(seconds=100).seconds
100.0
>>> TimeDelta(seconds=100).days
0.0011574074074074073
>>> TimeDelta(seconds=100).weeks
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: weeks
Guess I could add a .weeks attribute to mxDateTime, but no one ever
asked for that so far.
