Hm... I don't _think_ so. At least, I havent heard of any plans for
a High-Def upgrade to Usenet lately, but with Congress currently in
session I suppose anything is possible.

As for testing the clock's accuracy, you're right about needing a
second source ("Qui custodiet ipsos custodes?" or something like
that? grin). On the other hand, as long as the digits are
flashing by, I'm happy to "just trust them".


One needs three clocks.. if you have only two, you only know that they
differ. If you have three, you can detect the failed clock, because the
other two read the same time.

Of course, if the different clocks have different accuracies or
reliabilities, that's another story.

For a more detailed treatment of such things, you might want to check
out the "Byzantine General" problem.


Based on the feedback from other posters, it's likely a consequence
of 10MHz propagation. A VLF RF signal like 60KHz reportedly does a
much better job of getting a readable signal to a wide area.

Although in my house (southern California), the 60 kHz signal seems to
fade in and out on a daily basis.
