-/***
- * 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
- * {@link org.apache.commons.net.DatagramSocketClient#open open }
- * and call {@link #getTime getTime } to retrieve the daytime
- * string, then
- * call {@link org.apache.commons.net.DatagramSocketClient#close close }
- * to close the connection properly. Unlike
- * {@link org.apache.commons.net.daytime.DaytimeTCPClient},
- * successive calls to {@link #getTime getTime } are permitted
- * without re-establishing a connection. That is because UDP is a
- * connectionless protocol and the Daytime protocol is stateless.
