"Nwxt there is no such thing as "time!" Well, the illusion called time is useful in physics, navigation, etc. It gives some people something to sell. Man has struggled desperately to measure time sccurately through much of history. The cesium beam atomic clock is about the best standard now. First produced by the U.S. NIST in 1952 as NBS-1. England`s National Physical Laboratory atomic clock is accurate to one second in 1000 years. Best regards, Richard Harrison, KB5WZI |
