The recent discussion in sci.electronics regarding the accurate setting
of clocks prompts this curiousness:

How do long-distance telephone services maintain accuracy in
time-stamping telephone connections?
Precisely, how, and how often, are such clocks set, and what is their
accuracy?

I had no success in gleaning this information from customer service
representatives at MCI and AT&T.  I suppose this question is so unusual
that they did not know the answer, nor know how to get the answer.

Thank you,
John.
