static constexpr time_point min() noexcept; // C++20

概要

最小のtime_pointを取得する

戻り値

time_point(duration::min())

• min()[link /reference/chrono/duration/min.md]

例

#include <iostream>
#include <chrono>

using namespace std::chrono;

int main()
{
  time_point<system_clock> p = time_point<system_clock>::min();

  std::cout << p.time_since_epoch().count() << std::endl;
}

• min()[color ff0000]
• system_clock[link /reference/chrono/system_clock.md]
• time_since_epoch()[link time_since_epoch.md]
• count()[link /reference/chrono/duration/count.md]
