That will do little good and maybe some harm. ntpd reads time stamped
input. Even if this sits in a buffer unprocessed it's OK because the
critical work, the stamping is done inside an interrupt handler.
Running a process at RT priority when it does not need to can take
away CPU time from other processes and harm overall system
If you are concerned about offset the solution is to use a good local
