In configuring this WWVB clock, what should I set the "precision" to?
It's accurate down to milliseconds (supposedly), so should I use
2**-10 (= 1000Hz)?  On the other hand, the driver only grabs the
seconds and "guesses" on the milliseconds based on 9600 baud and
how many characters there are.  So maybe I should be using something
less precise?

The example in the ntpd doc for the PSTI clock says "-5", so I'm
wondering if using "-10" would be over-exaggerating.  The machine I
will be plugging is a Sun (100Hz = 2**-7 clock).

I'm so confused...
