On Linux, you could set a different kernel clocksource. Perhaps to jiffies or pit, if available. Check these files: /sys/devices/system/clocksource/clocksource0/current_clocksource /sys/devices/system/clocksource/clocksource0/available_clocksource Why not degrade the resolution of the clock directly in ntp sources?
