New submission from Alexander Belopolsky: With TZ=America/New_York,
>>> from datetime import * >>> u = datetime(2015, 11, 1, 5, tzinfo=timezone.utc) >>> t = u.astimezone() >>> print(t) 2015-11-01 01:00:00-04:00 >>> print(t.astimezone()) 2015-11-01 00:00:00-05:00 which is wrong - the second call to astimezone() should not change the timezone. Note that pure python code does not have this bug. (Try setiing sys.module['_datetime'] = None before running the code above.) ---------- components: Extension Modules messages: 262239 nosy: belopolsky priority: normal severity: normal stage: needs patch status: open title: A bug in datetime.astimezone() method type: behavior versions: Python 3.5, Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26616> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
