FYI, that invariant failed for me just now under the released 3.4.3 too: Python 3.4.3 (v3.4.3:9b73f1c3e601, Feb 24 2015, 22:44:40) [MSC v.1600 64 bit (AMD64)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> from datetime import * >>> E = datetime(1970,1,1,tzinfo=timezone.utc) >>> s = -1/2**7 >>> datetime.fromtimestamp(s, timezone.utc) datetime.datetime(1969, 12, 31, 23, 59, 59, 992187, tzinfo=datetime.timezone.utc) >>> E + timedelta(seconds=s) datetime.datetime(1969, 12, 31, 23, 59, 59, 992188, tzinfo=datetime.timezone.utc) It's an exactly-tied rounding case for the exactly-representable-in-binary s = -0.0078125. |
