Hi, I'm Clepsy. No, that's not clumsy, or someone who steals... The name has to do with water clocks, one of the earliest methods of keeping time, precisely. In my career, being even one second off would add upwards of a quarter of a mile to your position error. A minute off would throw your position off by more than 16 miles. Precise timing was absolutely critical! My line of work required using multiple sources of navigator information in order to minimize error, hence, "Clepsydrae," the plural of "Clepsydra." In ancient times, some ancient philosopher realized by measuring the errors of multiple water clocks, and using those errors to correct the measurements of each, while averaging the measurements of multiple corrected water clocks, one could arrive at a very precise time worthy of modern navigation. Believe it or not, this is very close to how we navigated all over the world using a simple sextant, an accurate watch, charts, tables, some additional equipment and well-practiced procedures.
