(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(duration::max()).
[edit] Parameters
(none)
[edit] Return value
The largest possible time_point.
[edit] 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); }
