Thank you, those two fixes took care of the problem.

The issue here is that you've done two different imports at the top:
import datetime
from datetime import *
These are incompatible with each other, so you're going to get issues.
I'd recommend doing just the first one, and then identifying d2 as
datetime.datetime.now() instead.
