Yes.

The new 'perf trace' utility - which might be the straightforward 'report a trace' 
utility that David is looking for is still WIP and can be found at:

  git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git tmp.perf/trace

Warning: the code is stale and needs much more work to become mergable. But 
displaying GTOD timestamps is very much something that looks sensible in the 'perf 
trace' context as well.

Thanks,

	Ingo
