международная шкала координированного времени, UTC
Шкала времени, рассчитываемая Международным бюро мер и весов так, что смещение относительно Международной шкалы атомного времени составляет целое число секунд, а относительно шкалы всемирного времени не превышает 0,9 с.
[ГОСТ 8.567-99]
международная шкала координированного времени
Шкала времени, на основе которой осуществляется координированное распространение по радио стандартных частот и сигналов времени. Международная шкала координированного времени соответствует международному атомному времени, но отличается от него на целое число секунд.
Примечания.
1. Применительно к требованиям настоящего стандарта применяется "Национальная шкала координированного времени Российской Федерации UTC (SU)".
2. Международная шкала координированного времени устанавливается Международным комитетом мер и весов и Международной службой вращения Земли

Coordinated Universal Time, UTC
time scale which forms the basis of a coordinated radio dissemination of standard frequencies and time signals. It corresponds exactly in rate with international atomic time, but differs from it by an integral number of seconds.
NOTE 1 Coordinated universal time is established by the International Bureau of Weights and Measures (BIPM) and the International Earth Rotation Service (IERS).
NOTE 2 The UTC scale is adjusted by the insertion or deletion of seconds, so called positive or negative leap seconds, to ensure approximate agreement with UT1.

coordinated universal time, UTC

temps universel coordonné, UTC
échelle de temps qui constitue la base d'une diffusion radioélectrique coordonnée des fréquences étalon et des signaux horaires, qui a la même marche que le temps atomique international, mais qui en diffère d'un nombre entier de secondes
NOTE 1 Le temps universel coordonné est établi par le Bureau international des poids et mesures (BIPM) et le Service international de la rotation de la Terre (IERS).
NOTE 2 On ajuste l'échelle UTC par insertion ou omission de secondes dites secondes intercalaires positives ou négatives pour assurer sa concordance approximative avec l'échelle UT1
