[time-nuts] Question on crystal jumps

[Ian Sheffield]

You probably know that the combined effects of the Moon and Sun changes the 
rate of a pendulum clock by up to 1 part in 10 to the 7th, but that is a 
smooth sine rather than a jump. That shouldn't affect quartz either.

I agree with other posters - you are probably seeing the quantization of 
space/time ;-)

Ian.
