accuracy in the mm/s range, and from that get a very good rotation rate.

That would depend on whether the Martian year is an exact multiple of 
the Martian sol (which I suspect it is not), and then, whether you want 
your calendar to align with some astronomical event (e.g. a solstice).

1 mars sidereal year = 668.5991 sols
