[time-nuts] Another "atomic" clock question

Hi Hal

Not arguing for or against sawtooth or hanging bridges, etc. My needs for
GPSDO performance are unquantified but likely quite modest. I just want to
get something working that's a bit better than my OCXO. I don't think I
need the sawtooth stuff to get started.

One nasty problem with hanging bridges is that if you don't believe in them,
then you won't setup your monitoring system to notice them.
