choose

chrono I/O

C-style date and time
Defined in header <chrono>
enum class choose {

earliest,
    latest

};
 (since C++20)

The scoped enumeration choose can be passed to certain member functions of std::chrono::time_zone and std::chrono::zoned_time to control how ambiguous or nonexistent local times should be resolved. Passing choose::earliest causes the earlier time point to be returned, while passing choose::latest

If a choose is not passed and an ambiguous or nonexistent local time is encountered, a std::chrono::ambiguous_local_time or std::chrono::nonexistent_local_time
