Unfortunately, you're running into a known and documented limitation of time zone support in Django: https://docs.djangoproject.com/en/dev/ref/databases/#timestamp-columns > It seems like having USE_TZ = True is forcibly making my fixture dates > timezone aware, which I don't want.

Would it be possible to: - use USE_TZ = False during the migration process, - convert datetimes to the proper timezone while migrating, - then switch back to USE_TZ = True? Based on my understanding of your situation, I believe this is the easiest path if you want to use the ORM. Alternatives include: - pull data with raw SQL queries -- cursor.execute(...) -- and insert it into the main database through Django, - export data to a CSV file and re-import that. I hope this helps, -- Aymeric. -- You received this message because you are subscribed to the Google Groups "Django developers (Contributions to Django itself)" group.
