This article explores the origins of time measurement, the transition from astronomical clocks to atomic standards, how UTC and leap seconds are defined, and the technical mechanisms—especially NTP—that keep computers and devices precisely synchronized across the globe.
This article explores why clocks—both mechanical and computer—often lose accuracy, explains the physics behind the definition of a second, describes how atomic clocks and UTC were created, and details how network protocols like NTP synchronize system time while handling leap seconds and clock drift.
This article explores why clocks—both mechanical and computer—lose accuracy, explains the evolution from astronomical timekeeping to atomic standards, details how national time centers broadcast time, and shows how protocols like NTP synchronize devices while handling network delays and leap seconds.
