We are using runfcgi with protocol=ajp, with proxy_ajp on the Apache side. 
Works great here.

Except that setting TZ on every request doesn't solve the problem and
may just make it worse for multithread Apache MPM modules such as used
on Windows, or worker MPM on UNIX.

The only safe way to run multiple Django instances with different
timezone settings is to run them in separate processes using mod_wsgi
daemon mode or fastcgi type solutions.

We were encountering the same problem, as one django project was still
set to 'America/Chicago' instead of 'Europe/London' which is where we
are.  This appears to be a bug in the Django mod_python handler, so I
have added a ticket for it: http://code.djangoproject.com/ticket/7062

Magus on IRC told me that multiple django projects with different
timezones serverd by apache / mod_python could be a problem - ie one
changing TZ in a thread that also servers the other project.

So I set timezone-setting to Vienna/Europe for all of them and have
not seen then datetime-problem since 24hours. I think that was it.

Could this perhaps be that you are assigning datetime.now() (or  
equivalent) to a variable and then trying to use this? Which means  
that the value of that varible will be the date/time when apache is  
started/restarted (which could be at the same time everyday).

Thanks,

David

it's always 8 hours behind, but not reproducable. though it happens
everyday.

there are php sites running on the server.. well let's see if fastcgi
helps.

We had another problems with mod_python around year ago and we switched
to FastCGI. While not perfect, it does not give us any oddities like
race conditions coming from single-VM process (these times, mod_wsgi was
still maturing). May I suggest dropping mod_python and give mod_wsgi a try?

What version of Django are you using?, what deployment method
are you using? (mod_python, fast cgi, mod_wscgi).

datetime 8 hours off

2008-04-01 Thread Simon Oberhammer

hey group,
I have an inconsistant time problem, which goes away when I restart
apache, but then creeps up again after some time. When writing
comments in my custom app the time is 8hours behind (i'm CEST) *for
some users*. When I login with others, its okay.

in settings.py I have
TIME_ZONE = 'Europe/Vienna'

[EMAIL PROTECTED]:~/pm3$ date
Tue Apr  1 10:44:32 CEST 2008

any ideas what I should look for? This is annyoing.. it forces my to
apache2ctl restart quite often :-)

greetings
