[New-bugs-announce] [issue27711] datetime.utctimetuple() method should respect fold disambiguation

[Alexander Belopolsky]

New submission from Alexander Belopolsky:

With TZ = America/New_York:

>>> t0 = datetime(2016, 11, 6, 1, 30, fold=0)
>>> t1 = datetime(2016, 11, 6, 1, 30, fold=1)
>>> t0.utctimetuple()[:6]
(2016, 11, 6, 1, 30, 0)
>>> t1.utctimetuple()[:6]
(2016, 11, 6, 1, 30, 0)
>>> t0.timestamp()
1478410200.0
>>> t1.timestamp()
1478413800.0

The correct values for utctimetuple() should be the same as

>>> datetime.utcfromtimestamp(t0.timestamp()).timetuple()[:6]
(2016, 11, 6, 5, 30, 0)
>>> datetime.utcfromtimestamp(t1.timestamp()).timetuple()[:6]
(2016, 11, 6, 6, 30, 0)
