timestamp.py 'float' object is noniterable - I run this on my machine and it seems to work

import time, datetime

def timestamp_oldest(*args): new_list = sorted(args[0], reverse=True) return datetime.datetime.fromtimestamp(new_list[0])

posix_list = [] for _ in range(10): posix_list.append(time.time()) print(timestamp_oldest(posix_list))

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 time, datetime

def timestamp_oldest(*args):
    new_list = sorted(args[0], reverse=True)
    return datetime.datetime.fromtimestamp(new_list[0])

posix_list = []
for _ in range(10):
    posix_list.append(time.time())

print(timestamp_oldest(posix_list))

def timestamp_oldest(*args):
    return datetime.datetime.fromtimestamp(min(args))

Because of the way Unix times are recorded, the older times are smaller numbers. You can search for the minimum number from your list of *args. I found the above code floating around here before and thought it was pretty clever.
