Python 2.3 implements the datetime module in C, and datetime.{datetime,
date, time, timedelta, tzinfo} are implemented in C then.  Zope3 has a
workalike datetime module coded in Python, so that the same interface can be
used in Python 2.2.  datetime.{datetime, date, time, timedelta, tzinfo} are
implemented in Python then.  You can generally add new attributes to classes
implemented in Python, but generally not to classes implemented in C.
