from socket import *
import time, sys

port = int(sys.argv[1])         # Get port number
s = socket(AF_INET,SOCK_STREAM) # Create TCP socket
s.bind(("",port))               # Bind to port
s.listen(1)                     # Listen, but allow
                                #   only 1 connection
while 1:
    client,addr = s.accept()    #Get a connection
    print "Got a connection from ",addr
                                # Send time to client
    client.send(time.ctime(time.time()))
    client.close()
