So, just where is the bleeding edge of new time keeping technology??

This article at sciam.com pretty much redefines the lengths science is going to to achieve greater time keeping accuracy with wide ranging implications for many branches of science and in the long run day to day applications that you or I will come into contact with in the coming years. SCIAM is a subscription site but the front page summary gives a good indication of where things are headed. If you care to read further then a mild dose of pocket plastic is required and totally at your discretion. I hope this is of interest. |>

Hmmm, looks interesting, but AFAIK the speed of light is not completely constant as it can be bent around objects of immense mass and diffracted through various materials such as glass and water.

Presumably under laboratory conditions these anomalies aren't going to exist (or can be compensated for). I suspect the bottleneck is going to be in the instruments used to measure these light cycles. How long will it be before such instruments are going to be scaled down in both size and cost to fit on our wrists ?

Looks like the future is going to be bright after all ;-)
