Always use django's timezone.now() instead of datetime.now()

[devxpy]

If you’re writing a pluggable application that’s expected to work independently of the value of USE_TZ, you may find django.utils.timezone.now() useful. This function returns the current date and time as a naive datetime when USE_TZ = False and as an aware datetime when USE_TZ = True. You can add or subtract datetime.timedelta as needed.
