time_zone conflict.. datetime.now() (in django shell) shows 3 hours earlier

[alperkanat@…]

to make it clear, I replicate the problem:

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

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:

TIME_ZONE = 'Europe/Helsinki'

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

Seems like a bug.

[ebruning]

The behavior reported by Colin Grady is associated with an unknown TIME_ZONE. America/Pacific isn't on the list at ​http://en.wikipedia.org/wiki/List_of_tz_zones_by_name. Unknown time zones cause the time zone to default to UTC.

Since Europe/Istanbul as listed in the original ticket is a valid time zone, I'm not sure what's up. Could be as simple as a misspelling in settings.py.

Otherwise, with a time zone that I know is valid, this worksforme.
