A little‑known Windows feature called Secure Time Seeding (STS) can mistakenly reset system clocks by weeks or even years, causing chaos for administrators, and the only reliable mitigation is to disable the feature via a registry tweak.
The article explains why leap seconds are added to keep UTC aligned with Earth's rotation, describes the three time scales (UT1, TAI, UTC), details Linux kernel bugs caused by leap‑second handling across various versions, and offers mitigation scripts while discussing the future removal of leap seconds.
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.
