/***
 * This is an example program demonstrating how to use the DaytimeTCP
 * and DaytimeUDP classes.
 * This program connects to the default daytime service port of a
 * specified server, retrieves the daytime, and prints it to standard output.
 * The default is to use the TCP port.  Use the -udp flag to use the UDP
 * port.
 * <p>
 * Usage: daytime [-udp] <hostname>
