Oh actually that's my mistake. I can't reproduce the failure in the constructor in the Python version of the module, and also it seems to be fixed in the pure Python version as of at least 3.6: Python 3.6.7 (default, Oct 25 2018, 16:11:17) [GCC 8.2.1 20180831] on linux >>> import sys >>> sys.modules['_datetime'] = None >>> from decimal import Decimal as D >>> from datetime import datetime >>> datetime.utcfromtimestamp(D(123456.12345)) datetime.datetime(1970, 1, 2, 10, 17, 36, 123450) But the truncation behavior is still present in the C version as of Python 3.8.0a1+: Python 3.8.0a1+ (heads/master:3766f18, Feb 11 2019, 12:52:31) [GCC 8.2.1 20181127] on linux >>> from datetime import datetime >>> from decimal import Decimal as D >>> datetime.utcfromtimestamp(D(123456.12345)) datetime.datetime(1970, 1, 2, 10, 17, 36) I still think we need a test for the constructor behavior, but I'm going to remove "easy", since we still need to fix truncation in the C version. ---------- keywords: -easy _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue23607> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
