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