I cannot make this to work. Please help me!

Can anyone tell me what's wrong with my code?

import datetime

starter = datetime.datetime(2015, 10, 21, 16, 29)

# Remember, you can't set "years" on a timedelta!
# Consider a year to be 365 days.

## Example
# time_machine(5, "minutes") => datetime(2015, 10, 21, 16, 34)

def time_machine(integeer, timee):
    return datetime.datetime(2015, 10, 21, 16, 29).timee - integeer

Im on challenge 2 of 2 if someone could help me out, im stuck

You need to use timedelta(). Take a look at the docs to see how to use it. https://docs.python.org/3/library/datetime.html#timedelta-objects

You need to check the string (whether it's minutes, hours, days, or years) to pass in the correct parameter to timedelta. And as it says in the comments, you can't pass years to timedelta, so you'll need to figure out what to do if it's years.

Once you have the timedelta object, you can just return starter + that object. No need to rewrite what the starter is.
