Hi Adam. I'm trying to follow, and having a bit of a hard time,
perhaps because I'm trying to work too quickly. :-)
I thought you meant that the following test of zc.i18n.date.normalize
would fail:
>>> dt = datetime.datetime(2006, 5, 1, 10, tzinfo=pytz.UTC)
>>> normalize(request, dt)
datetime.datetime(2006, 5, 1, 10, 0, tzinfo=<UTC>)
However, I actually added this test to zc.i18n.date and it passed. I
checked it in (revision 69155), but I assume that means that I still
don't understand what the problem you identified is. Could you maybe
post a doctest that fails?
Thanks
Gary
