from django.utils import timzone 
This enables you to have a timestamp on any model if you create a 
DateTimeField.

For the date, you can use datetime.date.today() or datetime.datetime.now().date().

For the time, you can use datetime.datetime.now().time().

However, why have separate fields for these in the first place? 
Why not use a single DateTimeField? in Models

You can always define helper functions on the model that return the 
.date() or .time() later if you only want one or the other.
