Here you are:
To set your computer clock to NIST, almost exactly, download the
free program from:
This program will set your computer clock accurately to within 50 msec
or less of the NIST atomic clock. How? It will ping the connection between
your computer and the NIST atomic clock, measure the delay, and
compensate accordingly the recv'd time from NIST. If the NIST site
is busy when you happen to try, it switches automatically to the
US Naval Observatory clock and does the same process!
So far as I know, this "careware" program (for a definition of same,
see the site above) is the only program with "ping" compensation;
Atomic clock, Dimension 4, etc all can at best get you within
500 msec or so, sometimes not that good because of the randomness
of the path which the Internet will provide between you and NIST.
