.SH DESCRIPTION
This script uses \fBadjtimex\fP(8) to find values for the kernel
variables \fBtick\fP and \fBfrequency\fP that will make the system
clock approximately agree with the CMOS clock.  It then saves these
values in the configuration file \fI/etc/default/adjtimex\fP so the
settings will be restored on every boot, when
\fI/etc/init.d/adjtimex\fP, or systemd adjtimex.service, runs.
.P
\fPadjtimexconfig\fP uses the drift rate recorded in
\fI/etc/adjtime\fP to adjust the times it reads from the CMOS clock.
If you find the CMOS clock has a systematic drift, read the
\fBclock\fP(8) or \fBhwclock\fP(8) manual page, modify
\fI/etc/adjtime\fP as required, and run \fBadjtimexconfig\fP again.
