I have been following the discussion about accurate time for PCs. I'm at
work right now, but at home I have 4 or 5 programs that get the "exact"
time and update my computer, if I want. I don't have the need for
extremely accurate time, but the programs are interesting to use.
My main question is: which one is correct? I think all of them have their
time based on the atomic clocks at NIST, but I can switch from one program
to another and see a difference between them of up to nearly one
second. How does one know which one is the most accurate? I'm sure at
least two of the programs I use will first ping the server they are getting
the time from to get the delay, which seems necessary.
The radio I used to use to listen to WWV is broken, but perhaps that would
be a good way to find out which programs are WAY off!
