Aloha, But there is an even better and more accurate one, which
is also FREE! It "pings" the connection between you and NIST or
the Naval Observatory, adjusts the incoming signal depending
upon the measured path delay, and can set your computer
clock to within a few msec. Dimension 4 does not compensate
for Internet connection route delays, and is at best accurate to
around a half second or so; just in case you want real
accuracy, you can have it.
To set your computer clock to NIST, almost exactly, download the
free program from:
This program will set your computer clock with extreme accuracy.
If the NIST site is busy when you happen to try, this program
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.
