Such experimentation is unfeasible in C where more effort goes into thinking about integer overflow and reference counting than into actual design. Here are some of those issues: http://bugs.python.org/issue5516 = equality not symmetric for subclasses of datetime.date and datetime.datetime http://bugs.python.org/issue2736 = datetime needs an "epoch" method http://bugs.python.org/issue7584 = datetime.rfcformat() for Date and Time on the Internet http://bugs.python.org/issue1100942 = Add datetime.time.strptime and datetime.date.strptime http://bugs.python.org/issue8860 = Rounding in timedelta constructor is inconsistent with that in timedelta arithmetics http://bugs.python.org/issue1647654 = No obvious and correct way to get the time zone offset http://bugs.python.org/issue5288 = tzinfo objects with sub-minute offsets are not supported (e.g. UTC+05:53:28) http://bugs.python.org/issue1982 = Feature: extend strftime to accept milliseconds >> 3.

I completely agree and I think the sooner the python code gets into the main tree the more reviews it will get before the next release. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
