inetd.conf(5)
| Inetd provides several ``trivial'' services internally by use of
| routines within itself. These services are ``echo'', ``discard'',
| ``chargen'' (character generator), ``daytime'' (human readable
| time), and ``time'' (machine readable time, in the form of the
| number of seconds since midnight, January 1, 1900). All of these
| services are tcp based. For details of these services, consult the
| appropriate RFC from the Network Information Center.
