Time zone aware aggregation
~~~~~~~~~~~~~~~~~~~~~~~~~~~
The support for :doc:`time zones </topics/i18n/timezones>` introduced in
Django 1.4 didn't work well with :meth:`QuerySet.dates()
<django.db.models.query.QuerySet.dates>`: aggregation was always performed in
UTC. This limitation was lifted in Django 1.6. Use :meth:`QuerySet.datetimes()

aggregation on a :class:`~django.db.models.DateTimeField`.
