[New-bugs-announce] [issue25149] datetime.weekday() off by one if handling a date from utcfromtimestamp()

[AndreC]

New submission from AndreC:

I've stumbled over an odd datetime.weekday() behaviour in Python 2.7.8 (default, Jun 18 2015, 18:54:19)  [GCC 4.9.1] on linux2) under Ubuntu. weekday() is off by 1.

Code to reproduce:

from datetime import datetime
date = datetime.utcfromtimestamp(int('1410446564'))  # datetime.datetime(2014, 9, 11, 14, 42, 44)
date.weekday()  # should be 4, not 3

I can reproduce this behaviour on our dev and production systems, and just tested it locally with python 3.4.3.

Since I'm not a smart man, I might overlook something silly...
