Ok, I fixed Python 3.4 and 3.5 too: fromtimestamp() and utcfromtimestamp() now uses also ROUND_HALF_EVEN rounding mode, as timedelta constructor. I explained in Misc/NEWS that the change was made to respect the property:
(datetime(1970,1,1) + timedelta(seconds=t)) == datetime.utcfromtimestamp(t)
Thanks Alexander Belopolsky & Tim Peters for your explanation on rounding. It's not a simple problem :-)
Thanks Tommaso Barbugli for the bug report: it's now fixed on all (maintained) Python 3 versions: 3.4, 3.5 and 3.6. The fix will be part of Python 3.5.1. |
