strptime not strict enough

[Tobias Weber]

Hi,
despite the directives for leading zero stime.strptime('09121',
'%y%m%d') returns the first of December. Shouldn't it raise ValueError?

Where do I get strict date parsing?

Python merely calls the strptime function in your C run-time library.  If
it sucks, so will time.strptime.

Er, no, wrong: http://svn.python.org/view/python/trunk/Lib/_strptime.py?view=markup

Cheers,
Chris
