Hello, All:

I bought a so-called "atomic clock" two days ago, and it receives the
radio signals from NIST (National Institute of Standards and
Technology) to automatically adjust its time. And it works fine.

Meanwhile, I called the Verion telephone number [(757)622-9311 in
southern Virginia] which gives current time. To my surprise, I found
that the Verizon time is about four (4) seconds faster than the NIST
time.

What is the cause of this difference? Is it due to telephone
transmission delay? Or does Verizon use an independent clock that is
not synchronized with NIST?

At one point, I noticed that the time signal on KGO in San Francisco
was time delayed just like the talk shows. I complained that they
should either provide the exact time or stop making the appearance of
providing the exact time. (not have a time signal but just an
announcement)

Of course, time signals on RealAudio are never accurate - if nothing
else, and there almost always is, there's always a few seconds of
buffering.

How do XP internet-adjusted clocks compare to WWV, CHU, et alia?
