They use a cesium fountain at Boulder and here in Canada at the NRC. I wonder, do the Ancients have an even more accurate time source? You would not believe how important it is to have really accurate and precise timing in some applications.
Incidentally, I have to complain about satellite TV. It has been rainy and windy here, I had no signal at 8pm, so now I have to wait till 2am to see the repeat of Incursion. Being a week behind is bad enough, now I have to wait 4 more hours!
