Description (Last modified by ramiro)

to make it clear, I replicate the problem: 

[02:29] (tunix@penguix raptiye)$ date

>>> datetime.utcnow()

i've just set system time to UTC and it still doesn't work.. i'm using Europe/Istanbul as the timezone.. django would work fine a few weeks before..

I am also seeing strange behavior:

With the first TIME_ZONE setting, it seemed it might be respecting it, but changing to anything for Pacific time made it switch to UTC in manage.py shell
