[LinuxPPS] How to use PPS to adjust system clock time ?

One more if I may on this issue:
Is there a way to adjust system clock (from pps) in kernel instead of doing it in userland ? How ? (I ask because I am still not sure how to do this adjustment from userland, and might find that doing it in kernel it is simpler)

Thanks,
