Alexander Belopolsky added the comment: It your use case, the input "0001-01-01T00:00:00" was in what timezone?
I suspect what you want is >>> datetime.min.replace(tzinfo=timezone.utc).timestamp() -62135596800.0 And not -62135658000.0. If you work with naive datetimes and just want to roundtrip between datetimes and numbers, you should not use a timezone-dependent conversion - attach UTC timezone before calling .timestamp() as shown above. You probably don't want your program to produce different numbers for the same "0001-01-01T00:00:00" input depending on where it is run. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue31212> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
