For starters, amazing utility and just what I was looking for. Thank you for writing and maintaining this project.

If a model has a DateTimeField() and settings.py contains USE_TZ=True then I am receiving the following error:

/home/me/.pythonbrew/venvs/Python-2.7.2/myproject/lib/python2.7/site-packages/
django/db/models/fields/__init__.py:827: RuntimeWarning: DateTimeField
received a naive datetime (2010-12-22 18:30:51.443334) while time zone
support is active. RuntimeWarning)

ValueError: astimezone() cannot be applied to a naive datetime

I've got a workaround by doing the following in generators.py:

class DateTimeGenerator(Generator):
    from django.utils.timezone import now

    min_date = now() - datetime.timedelta(365 * 5)
    max_date = now() + datetime.timedelta(365 * 1)

The Django version of now() [1] returns a naive or aware datetime object according to the value of USE_TZ.
