def delorean(integer):
  #starter.hour must be the difference of the first starter.hour and integer
  #there is no negative time there for integer must be greater than starter.hour and less than or ==23
  if integer > starter.hour:
    return starter.replace(hour = integer - starter.hour)

So what if your starter hour is 22 (10 pm), and integer comes in as 5. Your code turns the hour into 27, which...well, doesn't exist. Since you're wanting to move backwards and forwards through time, you need to use timedelta() and not just replace hours or other units.
