[Mono-dev] high precision real & cpu time in MONO (on linux)

Hello All,

I am a newbie to Mono and to C# ; I am using only Debian/Sid/AMD64 on a
recent linux 2.6.29-rc3 kernel (with CONFIG_HIGH_RES_TIMERS CONFIG_HZ=1000)
, mono 2.2

I am searching for a way to measure real clock and cpu time with high
precision. The linux system call is clock_gettime.

Apparently mono has some way to get it, since mono-2.2 contains the file
mono/utils/mono-time.[ch] with functions 
  gint64  mono_100ns_ticks(void)  MONO_INTERNAL;
  gint64  mono_100ns_datetime  (void)  MONO_INTERNAL;
I blindly guess that MONO_INTERNAL would mean that these functions are not
accessible from C# 3.0 code.

What is the easiest way to get high precision (at least high resolution)
time on Linux? Ideally I would like to get CLOCK_REALTIME or CLOCK_MONOTONIC

But any way of measuring milliseconds real & cpu (preferably thread) time is

Any clues?
