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 <iostream>
      #include <vector>

      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
