Hi to all,

Sorry for my poor english.

1) What are reliable clocksources?

2) I have a mainboard with a 500 Mhz cpu which works perfectly with RT.
I suppose that the max resolution is 2 ns for the high resolution timers
but a "cat /proc/timer_list" reported:

cpu: 0
 clock 0:
  .index:      0
  .resolution: 1 nsecs <----

active timers:
 clock 1:
  .index:      1
  .resolution: 1 nsecs <----

How it is possible that this mainboard have 1 nsecs resolution?

Excuse me if it are stupid questions. 

Thanks in advance!

Ciao,
Alessio
