Django1.4 with USE_TZ=True needs timezone aware datetimes

[magopian]

If using Django1.4 and USE_TZ = True, the datetime objects used need to be timezone aware.

Using the django.utils.timezone helpers makes it usable wether the USE_TZ setting is set to True or False.

Second commit "uglifies" the code, but makes it compatible with 1.3.1 AND 1.4

What about something like:

try:
    from django.utils.timezone import utc
except ImportError:
    utc = None
return datetime.datetime(year=2008, month=7, day=1, tzinfo=utc)

I mean:

• same call to datetime.datetime()
• ability to move the try/import/except to the beginning of the module ?
