-     public final class DaytimeTCPClient
      extends SocketClient

  The DaytimeTCPClient class is a TCP implementation of a client for the Daytime protocol described in RFC 867. To use the class, merely establish a connection with `connect` and call `getTime()` to retrieve the daytime string, then call `disconnect` to close the connection properly.

    - #### getTime

          public String getTime()
                         throws IOException

      Retrieves the time string from the server and returns it. The server will have closed the connection at this point, so you should call `disconnect` after calling this method. To retrieve another time, you must initiate another connection with `connect` before calling `getTime()` again.
      Returns:
        The time string retrieved from the server.
      Throws:
        `IOException` - If an error occurs while fetching the time string.
