1.1.1dev: Slightly more robust handling of really old dates. `time.mktime()` can raise `ValueError` or `OverflowError` depending no platform / date. On Windows for example, dates before 1900 raise `ValueError`, dates between 1900 and 1970 raise `OverflowError`.

(See also http://bugs.python.org/issue1777412 for a related but unsolved problem where `datetime.strftime()` dislikes years before 1900, too.)
