I don't understand why these persons use civil time at all. Working with multiple clocks at a time is the reality of many. And, as far as i understand, they seem to have the environment to keep on going with the correct time, regardless. I.e., they can choose, whereas i can not (easily, at least). (Well. These bet on the live of the children of mothers still to be born, they, ~25 years ago, did move more money on a single day than entire humanity produces, exploits and generates in a whole year, with 20 year olds who move more money a day than more than just one entire nation generates in a whole year. What money is this? It doesn't exist. (And not even taking into account the debt level of the U.S. at that time.) So in my opinion it is not responsible to give these unreflected subjects control over resources and food, and life in general. It is however understandable that the necessity to assure a livelihood and or professional ambition demands working with these people.) It was an interesting reading (i skipped over the maths, of course), especially so the necessity for calibration and the interference factors that have been taken into account. It is fascinating to see how much we have learned, even though much of the physics and chemistry etc. is in active use whereas not fully understood. (Just yesterday i've read about the Haber-Bosch process, for example, which was in use a long time before it could be explained in detail, as far as i have understood.) All the physical values that are involved, tidals, tectonics, atmosphere denseness, earth rotation and position in the solar system, human-caused emissions, that makes it pretty impressive to end up with such a high accuracy, all over the world. --steffen _______________________________________________ LEAPSECS mailing list LEAPSECS@leapsecond.com https://pairlist6.pair.net/mailman/listinfo/leapsecs
