It sets the hardware timer only to interrupt when the next event has 
been scheduled to occur, rather than at a constant rate.  I believe it 
also uses heuristics to consolidate timer events, so that multiple 
events can be handled on each interrupt, even if they have slightly 
different due times.

I don't believe that ntpd will work on a tickless kernel build, at least 
not when using the more accurate kernel time discipilne.
