correzione occasionale del tempo coordinato universale per mantenerlo allineato al giorno solare medio
A leap second is an extra second that is occasionally added to our clocks to keep official timekeeping aligned with how fast the Earth is actually spinning. This adjustment matters because Earth's rotation is gradually slowing down, and without these corrections, our civil time would gradually drift out of sync with the sun's position in the sky.

Il secondo intercalare (in lingua inglese leap second) è una correzione del tempo applicata al tempo coordinato universale (UTC) per mantenerlo allineato al giorno solare medio. L'ente responsabile della sua misura e scansione temporale è l'International Earth Rotation and Reference Systems Service (IERS).
