Scientists who study Earth’s rotation use the term ‘length of day’ to talk about how slow or fast Earth is spinning. The length of day is the difference between the time it takes Earth to rotate once on its axis, and 86,400 seconds (which is 24 hours). When the length of day is rising, Earth is spinning more slowly. When it is decreasing and becomes a negative number, Earth is spinning more quickly.
Чочочочочо? 24 ч - это средние солнечные сутки. На деле же Земля совершает один оборот за приблизительно 23 часа 56 минут 4 секунды.
Если у вас часы каждые 15 дней убегают на час вперед, это повод сменить часы.
Да забей.
У них и географические полюса меняются в статье... (те, которые просто точки на карте).
Поменяться так-то могут только магнитные полюса.
