Unlike the U.S. Bureau of Standards' crude Cesium-133 atomic clock which errs by several seconds every 100,000 years; this Archimedian Chronometer, at the two predesignated time coordinates, is always right on. The US-BS's atomic clock is limited to time-delta demarcation accurate to only 1/9,192,631,770th of a second before having to introduce interpolation. Compare THAT to this chronometer which has a time interval so small that the display, like a sundial, appears to be without discontiguity (in fact, it progresses by quantum increments). To satisfy incredulous human scientists, an artificial flash sequence is introduced into the display. NOTE: no one has ever been able to detect any temporal deviation, however small! This scientific breakthrough (miraculously containing no mechanical or electronic moving parts) has survived every theoretical and practical challenge, including one founded upon Einstein's temporal distortionate theory of relativity.

At each of the two predesignated time coordinates you may set your time mechanism to an accuracy greater than that achievable by US-BS's atomic clock by importing our clock's setting. Clock's internal timing accuracy and precision are unaffected by environmental, electromagnetic, opinionated, or subspace anomalies. If the external display were to be interrupted by power failure, the internal accuracy and precision are maintained indefinitely until power is restored.

Your challenge: If you can show any temporal error at either of the two predesignated time coordinates the inventor will give you one of these valuable clocks. However, before sneeringly attempting to claim your prize, apprise yourself of these unsolicited acknowledgements: This World Book encyclopędia listing as sixth among sixty-six chronographs, and this astounded peer review.

Historical note: This clock's prototype was created by mechanical placement of paint molecules upon a potentially heat destabilized cardboard substrate. Amazingly, the prototype was as precise and accurate as the Internet-adapted production model. Unfortunately, someone laid a lit cigar on it before we could photographically preserve it for posterity.
