Except that they don't actually store days. They store 24 hour periods, which, because of timezones changing, is not the same thing. This is also clearly intended, for example timedelta allows floats, and will convert the fraction into seconds. And as you have repeated many times now, the datetime module's arithmetic is "naive" ie, it assumes that one day is always 24 hours. The problem with that assumption is that it isn't true. _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
