The trouble with the laser ring clock is that the earth moves and the mirrors lengthen the path on the south side if the beam is counterclockwise and shorten it on the north side. If you split the beam and send it both ways then I guess it would even out. But if the clock moved the pathlength would change and so would the perceived time. The interference figure that would be caused by the light beams co-inciding moves slowly clockwise (in the north) around the ring. Its rate of travel depends on the latitude as the ratio of the south length to the north length changes as you go north. If you knew the exact attitude and position of the ring, it would be a fair clock.

The GPS method of correcting time for the known position gives time accurate to 1 in 10^8 I think. Just a GPS at one locale and broadcast time would be better than say a timex.

The preceding has been pseudo scientific B.S. courtesy of the Brothers Grimm and a loose amalgam of the inflated hyperegomanical imagination and the wildest ravings of the certified street lunatic, Jeremiah P. Quigley-Jones (no fixed address, PA) . Any resemblance to a scientific theory is merely resonant with the depths of the average person's ignorance of physical world. If the preceding made any sense to you whatsoever you are urged to place yourself under psychatric care without delay.
