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.
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)

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)

5,727 PointsThank you Clayton. I had used the "-" instead of the "+" because I thought the question asked for before the start time.
