- * This program is an example using the DARPA "Daytime Protocol"
- * (see RFC 867 for the details) and the DARPA "Time Protocol"
- * (see RFC 868 for the details).
- *
- * BSD systems provide a server for both of these services,
- * using either UDP/IP or TCP/IP for each service.
- * These services are provided by the "inetd" daemon under 4.3BSD.
- *
- * inettime [ -t ] [ -u ] hostname ...
- *
- * The -t option says use TCP, and the -u option says use UDP.
- * If neither option is specified, both TCP and UDP are used.
