Regardless of the routing of your call (which may take the several seconds
you describe), the phone communication is approximately light-speed.  Yes,
there are finite delays involved in the switching circuitry, but remember
back to the most recent coast-to-coast phone call you made.  Did you notice
a big lag in talking to the other person?  I'll warrant not.  As far as I
know, the WWV dial-in is located in the continental US, (and probably some
place centrally located), so at least you will have a delay of

	2,000mi / 186,000mi/sec = .01 sec + electronics delay

(Or not very much delay at all).
