timestamp.py

Create a function named timestamp_oldest that takes any number of POSIX timestamp arguments. Return the oldest one as a datetime object.

Remember, POSIX timestamps are floats and lists have a .sort() method.

timestamp.py 
# If you need help, look up datetime.datetime.fromtimestamp()
# Also, remember that you *will not* know how many timestamps
# are coming in.
def timestamp_oldest(posix):
    posix.sort()
    return posix[0]

I also had trouble with this. After you build the function to handle a variable # of *args, carefully read the challenge prompt. It says "Remember, POSIX timestamps are floats..." and "Return the oldest one as a datetime object". You'll need to convert the timestamp into a datetime object w/ datetime.datetime.fromtimestamp()
