I'm still waiting for certain changes to core perf before I try again to 
get it committed. I haven't forgotten; it's just not ready yet.

And using the time-of-day patch against a newer kernel (tried 3.2, 3.4 
and 3.6) I do see the offset you mentioned. I'll need to look into it 
what to do. I'm traveling this week, so next week is the earliest.
