Thanks for your interrest.

I found some kernel docu:
http://www.mjmwired.net/kernel/Documentation/timers/

And:
http://lwn.net/Articles/167897/


Looks like HPET and RTC are hardware devices, where HPET is meant
to be superior and replace the RTC.

I still don't get: What is the HR-timer ?
I mean how does it compare to the HPET ?
When to decide for the HPET, when for the HRT  api ?
Does one if it depend on the other ?

The kernel-devs seem to distinguish between "high-resolution clock" (=hpet ??)
and HR-timer :
   " We used the high-resolution clock subsystem ontop of hrtimers to verify
152	the hrtimer implementation details in praxis ... "
