For those of you who want to dig deeper you can read copies
of old HP Journals at: www.hpl.hp.com/hpjournal/journal.html

In particular the articles related to synchronizing clocks in the
atomic era leading up to UTC are:

A New Performance of the "Flying Clock" Experiment

Correlating Time from Europe to Asia with Flying Clocks
http://www.hpl.hp.com/hpjournal/pdfs/IssuePDFs/1965-04.pdf

These four papers have always been a favorite of mine.
