WHILE we're on the topic of seconds, how could they (as in, how dare they) redefine the second so it no longer relates to the seconds of arc in a setting sun? The minute is supposed to be the time it takes a solar radius to pass the horizon! A pox on Cesium and the horse it rode in on!
Sorry.
Surely this was never the case. The Sun's apparent diameter changes with the Earth's distance from it. So a time unit defined in this way would change with the time of year.
