timestamp_oldest

What is wrong with my code? Thank you!

timestamp.py 
# If you need help, look up datetime.datetime.fromtimestamp()
# Also, remember that you *will not* know how many timestamps
# are coming in.
import datetime

def timestamp_oldest(*args):
    list1 = [*args]
    list2 = list1.sort()
    oldest = list2[0]
    return datetime.datetime.fromtimestamp(oldest)

Hey Ralph Hellstern, you are very close. The sort() method sorts a list in place and returns a None value. The leaves your list2 set to None.

Use simply list.sort() alone.

:point_right: change oldest to be derive from list1 and you should be golden!
