New submission from INADA Naoki: In [1]: import datetime
In [2]: datetime.datetime.utcfromtimestamp(0) Out[2]: datetime.datetime(1970, 1, 1, 0, 0) In [3]: datetime.datetime.utcfromtimestamp(0).replace(tzinfo=datetime.timezone.utc) Out[3]: datetime.datetime(1970, 1, 1, 0, 0, tzinfo=datetime.timezone.utc) datetime.utcfromtimestamp() returns naive datetime. But some methods assumes naive datetime is localtime. (e.g. datetime.timestamp()). This is big pitfall for many Pythonistas. We can't change default behavior for backward compatibility. How about adding `aware` keyword-only option? >>> datetime.datetime.utcfromtimestamp(0, aware=True) datetime.datetime(1970, 1, 1, 0, 0, tzinfo=datetime.timezone.utc) ---------- components: Library (Lib) messages: 230592 nosy: naoki priority: normal severity: normal status: open title: datetime.utcfromtimestamp() shoud have option for create tz aware datetime type: enhancement versions: Python 3.5 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue22791> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
