I am about to post -19 but I do not like the suggested change to go from timeticks to seconds.

Seconds is a fairly coarse unit.  I would not be surprised to see requirements for finer granularity in the future, even more so in virtualization and controller scenarios in which we start to see YANG being used.  There are applications that use single second periods today so I think it is entirely conceivable to see need for subsecond support down the line.  To allow periods only in units of seconds would seem to unnecessarily hobble ourselves.  Keeping things to timeticks is more futureproof IMHO.
