// This simple client program will connect to the simple server (from
// program JRServer.java) and get the current date/time.

			  // such as:
			  InetAddress addr =
				  InetAddress.getByName("java2b.javalab.cs.pitt.edu");
			  // or it can be as a raw address, such as:
			  //InetAddress addr =
			  //		   InetAddress.getByName("130.49.223.208");
