QUE SIGNIFIE LEAP SECOND EN ANGLAIS
Sauter en second lieu
Un deuxième pas est un ajustement d'une seconde qui est occasionnellement appliqué au temps universel coordonné afin de garder son heure proche de l'heure solaire moyenne. Sans une telle correction, le temps estimé par la rotation de la Terre dérive du temps atomique en raison des irrégularités dans le taux de rotation de la Terre. Étant donné que ce système de correction a été mis en place en 1972, 25 de ces dernières années ont été insérées. Le plus récent est arrivé le 30 juin 2012 à 23:59:60 UTC. La norme de temps UTC, qui est largement utilisée pour le chronométrage international et comme référence pour le temps civil dans la plupart des pays, utilise la définition du système international de la seconde, basée sur les horloges atomiques. Comme la plupart des normes de temps, UTC définit un regroupement de secondes en minutes, heures, jours, mois et années. Cependant, la durée d'une journée solaire moyenne est légèrement supérieure à 24 heures. Par conséquent, si la journée UTC était définie comme étant précisément 86400 secondes SI, l'heure UTC serait lentement différente de celle des normes basées sur l'énergie solaire, telles que Greenwich Mean Time et son successeur UT1.
