[Art] certainly lives up to his username. His Rubidium-standard atomic real-time clock is surely an example of hardware art. The substrate is a collection of point-to-point soldered perfboard modules.

provide them with the exact time and date thanks to accurate atomic clocks and the clever Network Time Protocol (NTP). But it wasn’t always like this: back in the 1990s when many computers didn ...

Researchers have explored the interplay between gravitational effects and quantum interactions in optical atomic clocks ... that define time in optical lattice clocks -- to change.

ESA's Atomic Clock Ensemble in Space (ACES) has arrived at NASA's Kennedy Space Center in Florida, United States. This ...

The Intercontinental Exchange (ICE), a global network of regulated exchanges and clearing houses for financial and commodity markets, has announced it will abandon its GPS-based timekeeping system in ...
