New submission from Matthew Earl:
datetime.datetime.strptime() without a year fails on Feb 29 with:
>>> datetime.datetime.strptime("Feb 29", "%b %d")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/auto/ensoft-sjc/thirdparty/lib/python3.3/_strptime.py", line 511, in
_strptime_datetime
return cls(*args)
ValueError: day is out of range for month
This is because without a year specified the year is assumed to be 1900, which
is not a leap year. The underlying _strptime._strptime() function has some
munging such that it doesn't itself fail (see #14157):
>>> _strptime._strptime("Feb 29", "%b %d")
((1900, 2, 29, 0, 0, 0, 0, 60, -1, None, None), 0)
...however datetime.datetime.__init__() is called with this tuple as *args,
causing the validation failure.
