Bummer! `time_machine` didn't return the right datetime.

import datetime
from datetime import timedelta

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(arg1: int, arg2: str):
    if arg2 == "hours":
        return (starter - timedelta(days=arg1/24))
    elif arg2 == "years":
        return (starter - timedelta(days=arg1 * 365))
    elif arg2 == "days":
        return (starter - timedelta(days=arg1))
    elif arg2 == "minutes":
        return (starter - timedelta(seconds=arg1 * 60))
