Are ancient water clocks reliable

Ancient water clocks, or clepsydras, were innovative timekeeping devices that relied on the steady flow of water to measure time. While they offered a more consistent measure than sundials, their reliability was affected by factors such as water temperature, impurities, and the design of the clock itself. Variations in water flow and evaporation rates could lead to inaccuracies. Overall, while helpful, they were not as precise as modern timekeeping methods.
