 /***
 24   
  * This is an example program demonstrating how to use the TimeTCPClient
 25   
  * and TimeUDPClient classes.  It's very similar to the simple Unix rdate
 26   
  * command.  This program connects to the default time service port of a
 27   
  * specified server, retrieves the time, and prints it to standard output.
 28   
  * The default is to use the TCP port.  Use the -udp flag to use the UDP
 29   
  * port.  You can test this program by using the NIST time server at
 30   
  * 132.163.135.130 (warning: the IP address may change).
 31   
  * <p>
 32   
  * Usage: rdate [-udp] <hostname>
