В кластер входят документы, посвященные механизму введения и влиянию високосных секунд на время и технологии, и не входят документы о других методах измерения времени.
Общие признаки: синхронизация атомного времени и вращения Земли, технические проблемы цифровых систем, корректировка UTC и UT1
Группа выше: Время и часовые пояса в информационных системах
Смысл: The main idea is that the discrepancy between Earth's slowing rotation and the precision of atomic clocks necessitates periodic 'leap seconds' to keep human timekeeping accurate, despite the potential for these adjustments to disrupt global digital systems.
Leap seconds synchronize atomic time with Earth's slowing rotation but can cause critical failures in digital infrastructure, leading to debates over whether to abandon them for less frequent corrections.
Смысл: The text informs readers about the addition of a leap second in June 2012 to synchronize atomic time (UTC) with the Earth's rotation (UT1), while mentioning the technical disputes regarding such adjustments.
A positive leap second will be added to UTC on June 30, 2012, to keep atomic time aligned with Earth's rotation, despite concerns from the US regarding system stability.
Смысл: The main idea is that leap seconds, once a viable solution for astronomical alignment, have become a liability for global computing infrastructure, leading Meta to advocate for their complete abolition to prevent systemic software crashes.
Meta advocates for the removal of leap seconds from UTC because they cause unpredictable software failures and infrastructure instability in modern distributed systems.
