high precision timers

the 'timer wheel' - which has low resolution works at jiffy resolution.
so usually it has precision of 1~10ms.

and there's high resolution timers in kernel to have nanosecond resolution,
but it doesn't seem to have nanosecond precision

is there a way to deal with high precision timers in kernel?
does it require specific hardware?
