Our caesium fountains are among only 12 worldwide. Meet the timekeepers who watch over them at the IST Metrology Division in New Delhi.

Abstract: Positioning with cellular networks can serve as a backup or as a complement to the Global Navigation Satellite System (GNSS), making it relevant for autonomous vehicle navigation with ...

As the timebase for a clock, almost anything with a periodic oscillation can be used. Traditionally, that meant a pendulum, but in our time, we’ve seen plenty of others. Perhaps none as unusual as ...

Candle clocks were once an easy way to build a clock without using complex mechanical devices: just observe how quickly a thin candle burns down, mark an identical candle with periodic gradations, and ...

To better understand the circadian clock in modern-day cyanobacteria, a research team has studied ancient timekeeping systems. They examined the oscillation of the clock proteins KaiA, KaiB, and KaiC ...

Abstract: This paper presents the analysis, design, and characterization of an on-chip ultra-low-power clock oscillator for sensor nodes, implemented in 130 nm BiCMOS technology. The design employs a ...

Although Windows 11/10 shows a 24-hour lock format on the lock screen, you can change it to a 12-hour format using this step-by-step tutorial. It is possible to change the lock screen clock format on ...
