Python Dates and Times in Python Let's Build a Timed Quiz App Simple Time Machine

What's missing from this simple time_machine challenge?

Is the time variable starter supposed to be on the inside of the delorean function? To be before, I subtracted the hours passed in to decrease the starter time. When I try it in my workspace, the code runs as expected.

time_machine.py
import datetime

def delorean(before_start):
    starter = datetime.datetime(2015, 10, 21, 16, 29)
    print(starter)
    jumped = starter - datetime.timedelta(hours=before_start)
    print(jumped)
    return jumped


jumped_started = delorean(4)
print(jumped_started)

import datetime
starter = datetime.datetime(2015, 10, 21, 16, 29) # move this out of function
def delorean(before_start):
    print(starter)
    jumped = starter + datetime.timedelta(hours=before_start) # + not -
    print(jumped) 
    return jumped


jumped_started = delorean(4)
print(jumped_started)

Thank you Clayton. I had used the "-" instead of the "+" because I thought the question asked for before the start time.
