+It is also useful to have a shell script, e.g., \fB/sbin/timehosts\fP,
which contains a call on \fInetdate\fP with arguments appropriate
to the local system, so that it is easy to set the time manually.
-.SH "netdate -l 30 udp dcn\-gateway tcp neighbor"

+.SH "netdate -l 30 udp dcn\-gate tcp neighbor"
+\fIDcn\-gate\fP is a hypothetical host which usually keeps time
accurate to within milliseconds of Coordinated Universal Time,
but may occasionally be eight hours off.
\fINeighbor\fP is a neighbor of the local host which keeps time
with moderate accuracy.
-The time will be set to that of \fIdcn\-gateway\fP if that and \fIneighbor\fP
+The time will be set to that of \fIdcn\-gate\fP if that and \fIneighbor\fP
agree to within thirty seconds, else it will not be set at all.
This is almost good enough for most circumstances, but won't do
when the local host's time is known to be wrong (e.g., after
a long downtime or a bad crash) and must be set to something.
If one of the hosts named is inaccurate or not responding, there is a problem.
-.SH "netdate -l 30 udp dcn\-gateway tcp neighbor neighbor2"
+.SH "netdate -l 30 udp dcn\-gate tcp neighbor neighbor2"

+even if \fIdcn\-gate\fP is far off as long as the two neighbors agree.
This is probably good enough for most cases.
One can arbitrarily gerrymander the vote for more insurance
(and less clarity), as in the following example.
-.SH "netdate\ udp\ dcn\-gateway\ dcn1\ tcp\ bbn\-unix\ localhost\ neighbor"
+.SH "netdate\ udp\ dcn\-gate\ dcn1\ tcp\ bbn\-unix\ localhost\ neighbor"

timekeepers, at least one of which keeps time independently from
-\fIdcn\-gateway\fP, one hopes.
+\fIdcn\-gate\fP, one hopes.
It is very likely that the time will be set to that one of those three
very accurate hosts, as long as at least two of them agree, or at least
one of them agrees with the neighbor or the local host's time.
If all the foreign hosts disagree, the time will not be set,
since \fBlocalhost\fP will be chosen as best.
-.SH "netdate\ \-l\ 3\ localhost\ localhost\ udp\ dcn\-gateway\ dcn1\ tcp\ bbn\-unix"
+.SH "netdate\ \-l\ 3\ localhost\ localhost\ udp\ dcn\-gate\ dcn1\ tcp\ bbn\-unix"

have the most accurate time.

%description
Netdate takes a list of names of Internet hosts as arguments, selects
the one that supplies the best time, and sets the system time
accordingly.
The "best" time is chosen by polling the named hosts once each to find
their times and taking their differences from the local host's time.
These differences are used to find the largest group of hosts whose
times agree with each other within a certain limit. The first host in
the largest group is picked as the best host.
