I run an online game with Django 1.6 and Celery 3.1.11. Kombu is 3.0.15.
Recently I had problems with Celery and DST, so I decided to run the
whole site on UTC and save myself the bother of worrying about
timezones.
The relevant parts of my settings.py:
TIME_ZONE = 'UTC'
USE_TZ = True
....
CELERY_ENABLE_UTC = True
CELERY_TIMEZONE = 'UTC'
Now, whenever I send any delayed task, I see a bunch of
RuntimeWarnings that complain about naive datetimes. I went into my
settings.py and turned this into an exception, and this is the traceback
that resulted:
[2014-04-18 15:03:49,748: INFO/MainProcess] Received task: sometask[sometaskid] eta:[2014-04-19 00:33:32.410032+00:00]

As you can see, none of the traceback is due to my code, so I do not
know how to proceed. I could merely leave the warnings in (if I recall
correctly, Celery defaults time offsets to the CELERY_TIMEZONE
in settings.py, and this is what I want anyway) but my OCD is screaming
out at me to get this fixed. Plus, I can't ctrl-F to find any warning
that are due to my code.
Any advice?
