The first Atmos clock was designed by Jean-Léon Reutter, an engineer in Neuchâtel, Switzerland, in 1928. [5] [6] [7] This noncommercial prototype, which predated the Atmos name but is now known unofficially as Atmos 0, was driven by a mercury-in-glass expansion device. The mechanism operated on temperature changes alone.

In 1909, Halbert P. Gillette explained about the state of the art around time clocks in those days: IBM time clock. Time clocks.
Next-generation clocks will likely be based on nuclear transitions in the 229m Th nucleus, as nuclei are shielded from external effects by the accompanying electron cloud, and the transition frequency is much higher than optical and ion clocks, allowing for much lower systematic uncertainty in the clock frequency.

The time is about to change again. Daylight saving time, which began on March 12, ends on Sunday, Nov. 5. That means brighter mornings but darker evenings when we fall back an hour to Eastern ...
The Clock of the Long Now, also called the 10,000-year clock, is a mechanical clock under construction that is designed to keep time for 10,000 years. It is being built by the Long Now Foundation . A two-meter prototype is on display at the Science Museum in London.
