The C libs standard is seconds since the epoch (1.1.1970). Python
returns this as floating point value with precision depending on
the accuracy of the underlying C lib.

Other possibilities are: COM dates, Julian Day Numbers, etc.

A Python extension wrapping all these things into nice Python
objects can be found here:
