Recently, the similar issue1562 "Decimal can't be subclassed useful" was rejected. In the discussion I found a reference to a former post, which precisely deals with datetime and timedelta: http://mail.python.org/pipermail/python-list/2005-January/300791.html The main argument is that the """base class has no idea what requirements may exist for invoking a subclass's constructor""" All python types behave this way: int, float, lists.
