Thank you for the response. I added a function to the model to convert
a datetime field into the needed format (def convert_time). Then I set
new_time = property(convert_time). If I iterate over the queryset I
can access each.new_time BUT I need the value in the queryset
(Model.objects.filter().values('new_time')). Unfortunately Iget an
attribute error.Thank you.
