Description
Loading a YAML fixture with a timezone aware DateTimeField in Django 1.4 will cause the following warning even if the field is defined with timezone information in the YAML file
django/db/models/fields/init__.py:808: RuntimeWarning: DateTimeField received a naive datetime (2012-08-27 13:01:56.784734) while time zone support is active.
Excerpt from testdata.yaml
[...] , insert_date: !!timestamp '2012-08-27 13:01:56.784734+00:00', [...]
The test data is loaded by adding "fixtures = testdata" at the start of a test case class.
This bug is mentioned in Django test suite - django/trunk/tests/modeltests/timezones/tests.py:SerializationTests
Note: the trick of "MyTests = override_settings(USE_TZ=False)(MyTests)" (from #17940) often does not work as expected, because you can then get "ValueError: SQLite backend does not support timezone-aware datetimes when USE_TZ is False" during fixture loading
