daytime

public final class daytime extends Object
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.

Usage: daytime [-udp]
