Guys, I'm in that point where I did it a million times and I probably started making it worse without noticing it. Can anybody help me here?
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(duration, unit):
if unit == 'minutes':
offset = datetime.timedelta(minutes = duration)
elif unit == 'hours':
offset = datetime.timedelta(hours = duration)
elif unit == 'years':
offset = datetime.timedelta(days = duration * 360)
return starter + offset

Treehouse Moderator 68,425 PointsYou are very close! I see the following errors:
- missing option for "days" units
- year has 365 days not 360
- no default value for
offset
which causes a "reference before assignment error
Post back if you need more help. Good Luck!!
