17274	"Regression: ""TIME_ZONE = None"" fails if ""USE_TZ = True"""	Daniel Swarbrick	nobody	"Until the recent addition of TZ-aware dates, setting ""TIME_ZONE = None"" in settings.py has worked fine, as stated in the comments:

# On Unix systems, a value of None will cause Django to use the same
# timezone as the operating system.

However, if ""USE_TZ = True"", any output of datetime objects in a template results in:

AttributeError: 'NoneType' object has no attribute 'upper'

Apparently the TZ is not being determined prior the TZ-conversion code.
