More clock memories...

I remember in school the wall clocks would synchronize. I assume their was a company that made what we would call a networked clock today. This synchronization would occasionally make the clock go backwards. 

HP at one time had a Cesium reference/clock in the lobby of their Santa Clara site. Supposedly it was also the 10MHz reference for the facility. This is the place where Apple is going to build the "spaceship." Sacrilege in my opinion.
