timekeeping standards

Timekeeping standards are systems used to measure and coordinate time consistently across the world. The most widely used standard is Coordinated Universal Time (UTC), which derives from precise atomic clocks and is adjusted for Earth's irregular rotation. UTC serves as the basis for time zones and helps synchronize clocks globally. To ensure uniformity, specific organizations, like the International Bureau of Weights and Measures (BIPM), establish and maintain these standards. The accurate measurement of time is crucial for various applications, ranging from daily activities to scientific research and communication technologies.
