They are inaccurate. True water clocks were based on water flowing into or out of a graduated container and the user could tell the time by looking at the graduation aligned with the water level. There were also pseudo water-clocks in which a pendulum kept time but the power was provided by water.True water clocks, whether of the inflow or outflow variety, required a steady rate of flow. This depends on the viscosity of water which is dependent on the ambient temperature. A change in temperature from 20 to 21 deg C produces a change in viscosity of approx 2%. This would cause a clock to lose half an hour in a day!
You can stop the clocks by not worrying about the clocks.
