A leap second is a one- second adjustment that is occasionally applied to Coordinated Universal Time (UTC), to accommodate the difference between precise time ( International Atomic Time (TAI), as measured by atomic clocks) and imprecise observed solar time ( UT1 ), which varies due to irregularities and long-term slowdown in the Earth's rotation.

協定世界時 （きょうていせかいじ、 英語: coordinated universal time [1], フランス語: temps universel coordonné [1] [注釈 1] ）とは、 国際原子時 (TAI) に由来する原子時系の時刻で、 UT1世界時 に同調するべく調整された基準時刻を指す [2] [注釈 2] 。 言語によって 頭字語 が異なるため、共通の略称として UTC が定められている。 概要. 協定世界時は 国際度量衡局 (BIPM) が 国際地球回転・基準系事業 (IERS) の支援を受けて維持する時刻系で、 標準周波数 と 報時 信号発射の基礎であり、 国際単位系 (SI) 秒 に基づく国際原子時と同歩度 [注釈 3] だが、整数秒だけ異なる。
UTC (Engels: Universal Time Coordinated; in het Nederlands ook aangeduid als gecoördineerde wereldtijd) is sinds 1972 een internationale tijdsaanduiding, gebaseerd op een atoomklok en gecoördineerd met de rotatie van de aarde.Deze standaardtijd is de opvolger van Greenwich Mean Time (GMT) en verschilt daar nooit meer dan een seconde van. De gecoördineerde tijd is van belang wanneer tijden ...

Coordinated Universal Time (shqip: Koha e Koordinuar Universale), njohur edhe si UTC, është referenca kryesore e orëve dhe e kohës, sipas së cilës ndahet Toka në zona kohore. Ky standard është përndryshe pasardhësi i Greenwich Mean Time (GMT). Koordinimi i transmetimeve të frekuencave dhe të kohës u vendos më 1 janar 1960.
