This is most of the transition to Django 1.4 `USE_TZ = True`. We need to ensure we don't mix aware and non-aware datetime objects when dealing with datetimes in the code. Add a utc_now() helper method that we can use most places, and ensure there is always a timezone attached when necessary. Signed-off-by: Dan McGee <dan@archlinux.org>
