Actually, what you really probably want is middleware, if the setting is going to affect the template that’s chosen in the first place, or substantially affect the response. It is a good deal more flexible than using a template context processor, which is more appropriate if you simply want to add a couple variables to your context.

You create a middleware.py in your app, which might contain something like:

from django.conf import settings

class MyMiddleware(object):
    def process_request(self, request):
        request.my_app_setting = settings.MY_APP_SETTING

Don’t forget to add your class to your MIDDLEWARE_CLASSES setting.

You can use custom template context processors for passing “global” context to your views.

To accomplish this, create a new contextprocessors.py somewhere in your application with code similar to the example below (all it has to do is return a dict). Then add the path to the file with the function in the TEMPLATE_CONTEXT_PROCESSORS tuple in your settings.py (ie: yourapp.contextprocessors.resource_urls). 

from django.conf import settings

def resource_urls(request):
    """Passes global values to templates."""

    return dict(
        TIME_ZONE = settings.TIME_ZONE,
    )

Now you can refer to these keys in your templates as expected: {{ TIME_ZONE }}.
