Eh? In your example code from before you look to be keeping the system_time and error values in shifted nsec units. from your example: > // at init: system_update = update_cycles * mult; > system_time += system_update; and: > error = system_time - (xtime.tv_nsec << shift); This doesn't seem to make sense with the above.
