    Probably a little early. -hp- was experimenting with atomic 
clocks in the 1960s when  I worked for them. I think we had a 
quartz crystal clock in our facility as a standard for counters, 
etc. Ours was checked continuously against WWVB using a chart 
recorder to indicate continuous phase. I am not sure what WWVB 
was using as a standard then but think an atomic clock. Could 
look all this stuff up instead of relying on my somewhat rusty 
memory.
