Структура system_clock
Часы, основанные на часах системы в режиме реального времени.
Синтаксис
Remarks
Это время представляет собой часы системной стены.
system_clock Не является system_clock или постоянным.
Часы считаются постоянными, если они монотонны и интервал времени между соседними тактами является постоянной величиной. Поскольку system_clock не является монотонным, он не является постоянным, хотя время между тактовыми тактами является константой. Вы можете использовать только устойчивые часы, чтобы занять время до события, время после события и надежно вычесть их для получения длительности события, так как в течение этого времени постоянно не изменяются устойчивые часы.

is_steady
Статическое значение, указывающее, является ли тип часов устойчивым. Так как system_clock это не стабильно, вы не можете использовать часы, чтобы занять время до события, время после события и надежно вычесть их для получения длительности события, так как часы могут быть скорректированы в течение интервала времени.

Remarks
Часы считаются постоянными, если они монотонны и интервал времени между соседними тактами является постоянной величиной. system_clock Не является монотонным, так как значение, возвращаемое первым вызовом, now() не всегда меньше или равно значению, возвращаемому в результате более позднего вызова, now() поскольку системное время может быть скорректировано без уведомления.
Статический метод, возвращающий текущее время стены системы.
