As near as I can tell, this is a problem with Django / Jython
compatibility and not my code... if I'm wrong feel free to slap my
wrist...
A form was created with the following field:
start_date = forms.DateTimeField(required=True,
widget=forms.DateTimeInput({'class': 'datetime'}))
The following POST data was passed:
start_date u'11/03/2012 00:00:00'
The following traceback was received when I check for form.is_valid() in
the view:

At 441, format = '%Y-%m-%d %H:%M:%S.%f'
The %f formatting character was introduced in Python 2.6, but it is not
supported in Jython, even in the 2.7 alphas.

I remember this code working fine in Django 1.4.1, but I cannot seem to
find a commit that would have broken it during the timeframe between the
1.4.1 and 1.4.2 releases.

Comment:
Given that this is a known bug in Jython, I'm not sure what the right
response is here. The %f is needed to fix the problem from #9459; the
right solution would seem to be "Fix Jython", not "put in a workaround in
Django".

Comment (by fvox13):
I agree that Jython is the right place to put the fix. However, as it
stands right now, our documentation is wrong, because it states that we
are compatible with Jython 2.5, when we're not. Some mention of this bug
should appear here: https://docs.djangoproject.com/en/1.4/howto/jython/
especially given how common DateTimeField usage is.

Comment:
Marking as a duplicate of #20517 which suggests documenting Jython issues
on a wiki page. I've made a note of this issue on that ticket.
