Bummer! Didn't get back the correct datetime

This code seems to work perfectly when I run it in my own code editor and console, but I keep getting a bummer message when I submit it. What am I doing wrong?

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):
    time = []
    for item in args:
        time.append(datetime.datetime.fromtimestamp(item))
    return max(time)

I like your idea of using the max function instead of the sort() function that they recommended for some reason. The only problem is that timestamps get larger as time goes on, and in this example they want the oldest time, not the newest one, so you just have to use min(time) instead of max. :)
