Some machines do not hold time well with the default tickadj. If you have adjusted your tickadj to make ntpd work reasonably well (~100ppm) then you might find this useful to automatically save and restore your tickadj values at boot or service start/stop/restart.
It looks for a /etc/ntp/tickadj.conf and if it exists it sets tick to the value held there. On stop it stores the current tick value to this value.
