Dear @nicfar1708,

Thanks for identifying the problem and proposing a fix and sorry for the slow response time!

I think there's a simpler and more general solution: instead of fixing the insertion, we could fix the model defaults to use a callable:

  # Instead of (evaluated once at import):
  default=datetime.datetime.now(datetime.timezone.utc)

  # Use (evaluated each time):
  default=lambda: datetime.datetime.now(datetime.timezone.utc)

There are a few more instances of the problem than the ones you identified (you can find them by searching for default=datetime).

Would you like to try this fix?
