public final class DaytimeUDPClient extends DatagramSocketClient
The DaytimeUDPClient class is a UDP implementation of a client for the Daytime protocol described in RFC 867. To use the class, merely open a local datagram socket with open and call getTime to retrieve the daytime string, then call close to close the connection properly. Unlike DaytimeTCPClient, successive calls to getTime are permitted without re-establishing a connection. That is because UDP is a connectionless protocol and the Daytime protocol is stateless.
