辅助类

formatter<std::chrono::year>

hash<std::chrono::year> (C++26)

 

static constexpr std::chrono::year min() noexcept;		(自 C++20 起)

返回最小的可能 year，即 std::chrono::year(-32767).

返回值

std::chrono::year(-32767)

示例

运行此代码

#include <chrono>
#include <iostream>
 
int main()
{
    std::cout << "The minimum year is: " << (int)std::chrono::year::min() << '\n';
}

输出

The minimum year is: -32767
