IIRC, NTP turns a computer clock into a DO with millisecond accuracy.

Accuracy is stratified, with a number of Stratum 1 sources available.

Don't know if anyone has designed a collection of differentiated silicon
and stored programs that hooks to the internet and delivers a disciplined
10 MHz at 50 ohms.

Probably not, since even crystal oscillators do better than NTP. Beat
one against WWV and you were good to 10-7 or so.

Mills was working on microsecond accuracy five years ago. Where does
NTP stand now?
