Well, part of the problem is that you didn't really explain, why your 
logical are better in any way. You broke them out of your big patch and 
they lose their context.
It's probably better to first to understand and agree on the functional 
changes, moving code around can still be done afterwards.

I don't mind the clear interface...

The point is you're starting at the wrong point, first we need a clean 
clock interface, only then should we change the ntp code to it.
(More again in the next mail.)
