std::chrono..._point::max(3)  C++ Standard Libary std::chrono..._point::max(3)

NAME
       std::chrono::time_point::max - std::chrono::time_point::max

Synopsis
	  static constexpr time_point max();	       (until C++20)
	  static constexpr time_point max() noexcept;  (since C++20)

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

Parameters
	  (none)

Return value
	  the largest possible time_point

Example
       // Run this code

	#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
