static constexpr time_point max();

Restituisce un time_point con la durata più grande possibile, vale a dire std::chrono::time_point(std::chrono::duration::max()).

Original:

Returns a time_point with the largest possible duration, i.e. std::chrono::time_point(std::chrono::duration::max()).

Esempio

#include <chrono>
#include <vector>
#include <iostream>

int main() 
{
    std::chrono::time_point<std::chrono::system_clock> now =
        std::chrono::system_clock::now();
    std::vector<std::chrono::time_point<std::chrono::system_clock>> times {
        now - std::chrono::hours(24),
        now - std::chrono::hours(48),
        now + std::chrono::hours(24),
    };  
  
    std::chrono::time_point<std::chrono::system_clock> earliest =
        std::chrono::time_point<std::chrono::system_clock>::max();

    std::cout << "all times:\n";
    for (const auto &time : times) {
        std::time_t t = std::chrono::system_clock::to_time_t(time);
        std::cout << std::ctime(&t);
    
        if (time < earliest) earliest = time;
    }

    std::time_t t = std::chrono::system_clock::to_time_t(earliest);
    std::cout << "earliest:\n" << std::ctime(&t);
}

Possible output:

all times:
Sun Oct  7 19:06:48 2012
Sat Oct  6 19:06:48 2012
Tue Oct  9 19:06:48 2012
earliest:
Sat Oct  6 19:06:48 2012
