  * The DaytimeTCPClient class is a TCP implementation of a client for the
 24  
  * Daytime protocol described in RFC 867.  To use the class, merely
 25  
  * establish a connection with
 26  
  * {@link org.apache.commons.net.SocketClient#connect  connect }
 27  
  * and call {@link #getTime  getTime() } to retrieve the daytime
 28  
  * string, then
 29  
  * call {@link org.apache.commons.net.SocketClient#disconnect  disconnect }
 30  
  * to close the connection properly.
