The real-time clock (RTC)–as distinct from the processor clock, but often using the same source–is a critical function in many system designs. Depending on the application, it may need to be accurate ...

Researchers from the Purple Mountain Observatory in China released LTE440, short for Lunar Time Ephemeris, in a recently ...

Atomic clocks will only see a loss of 1 second in accuracy over a period of 10 million years. They are used in multiple ways, including the GPS in your car. Now researchers have found a way to bypass ...

The European Space Agency’s ACES mission could ultimately pave the way for a global network of atomic clocks that make these measurements far more accurate. In 2003, engineers from Germany and ...

A team of physicists has discovered a surprisingly simple way to build nuclear clocks using tiny amounts of rare thorium. By ...
