The -R option tells chronyd to ignore the makestep directive. A script
could add it to the chronyd command line when uptime is more than few
minutes for instance. However, I suspect this would be confusing. I
think users have learned to restart the NTP service when the clock is
wrong, e.g. when resume in a VM didn't work as expected, or the clock
was incorrectly set by a wrong date command. If they didn't know the
-R option was added automatically, they would have to reboot the
machine.
