New submission from Alexander Belopolsky <alexander.belopol...@gmail.com>:
Let g be a an invalid time in New York spring-forward gap: >>> g = datetime(2020, 3, 8, 2, 30) According to PEP 495, conversion of such instance to UTC should return a value that corresponds to a valid local time greater than g, but >>> print(g.astimezone(timezone.utc).astimezone()) 2020-03-08 01:30:00-05:00 Also, conversion of the same instance with fold=1 to UTC and back should produce a lesser time, but >>> print(g.replace(fold=1).astimezone(timezone.utc).astimezone()) 2020-03-08 03:30:00-04:00 Note that conversion to and from timestamp works correctly: >>> print(datetime.fromtimestamp(g.timestamp())) 2020-03-08 03:30:00 >>> print(datetime.fromtimestamp(g.replace(fold=1).timestamp())) 2020-03-08 01:30:00 ---------- assignee: belopolsky messages: 362241 nosy: belopolsky, p-ganssle priority: normal severity: normal status: open title: datetime.astimezone() method does not handle invalid local times as required by PEP 495 type: behavior versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39680> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
