If you want precision timing, then you want atomic clocks. These time pieces are able to pick up communications from the Cesium Atomic Clock Time Keeper in Colorado. With that as a standard, and with the ability to pick up signals, this clock is always as accurate as a clock can be. Regulators make charming additions to the home as well. These are clocks with simplified internal mechanisms, eliminating extraneous moveable parts. They are often used as a standard for other clocks, as they can be so precise.
