    Clock is a timekeeping mobile app available since the initial launch of the iPhone and iPhone OS 1 in 2007, [1] with a version later released for iPads with iOS 6 (however could unofficially be installed before [2]), [3] and Macs with the release of macOS Ventura. The app consists of a world clock, alarm, stopwatch, and timer.

    The app is similar in functionality and design to the Clock app on iOS. Windows Clock was available on mobile devices for over a decade before it was available on PCs with the introduction of Windows 8.1. [3] Tiles for alarms, timers, and the stopwatch can be pinned to the Start menu. The latest version of the app uses the Universal Windows ...

  4. Year 2038 problem - Wikipedia

    en.wikipedia.org/wiki/Year_2038_problem

    The problem exists in systems which measure Unix time—the number of seconds elapsed since the Unix epoch (00:00:00 UTC on 1 January 1970)—and store it in a signed 32-bit integer. The data type is only capable of representing integers between −(2 31 ) and 2 31 − 1 , meaning the latest time that can be properly encoded is 2 31 − 1 ...

  5. Unix time - Wikipedia

    en.wikipedia.org/wiki/Unix_time

    In the theoretical case when a negative leap second occurs, no ambiguity is caused, but instead there is a range of Unix time numbers that do not refer to any point in UTC time at all. A Unix clock is often implemented with a different type of positive leap second handling associated with the Network Time Protocol (NTP). This yields a system ...

    Early clock dials did not indicate minutes and seconds. A clock with a dial indicating minutes was illustrated in a 1475 manuscript by Paulus Almanus, [48] and some 15th-century clocks in Germany indicated minutes and seconds. [49] An early record of a seconds hand on a clock dates back to about 1560 on a clock now in the Fremersdorf collection.

    The Clock was moved to 150 seconds (2 minutes, 30 seconds) in 2017, then forward to 2 minutes to midnight in 2018, and left unchanged in 2019. [6] It was moved forward to 100 seconds (1 minute, 40 seconds) in 2020, [ 7 ] 90 seconds (1 minute, 30 seconds) in 2023, [ 8 ] and 89 seconds (1 minute, 29 seconds) in 2025.

  8. Atomic clock - Wikipedia

    en.wikipedia.org/wiki/Atomic_clock

    The SI second is defined as a certain number of unperturbed ground-state hyperfine transitions of the caesium-133 atom. Caesium standards are therefore regarded as primary time and frequency standards. Caesium clocks include the NIST-F1 clock, developed in 1999, and the NIST-F2 clock, developed in 2013. [67] [68]

    One octillionth of a second. yoctosecond: 10 −24 s: One septillionth of a second. jiffy (physics) 3 × 10 −24 s: The amount of time light takes to travel one fermi (about the size of a nucleon) in a vacuum. zeptosecond: 10 −21 s: One sextillionth of a second. Time measurement scale of the NIST and JILA strontium atomic clock.
