NAME

std::chrono::choose - std::chrono::choose

Synopsis

Defined in header <chrono>
enum class choose {

earliest, (since C++20)
latest

};

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 causes the later
time point to be returned. (For nonexistent local times, these two time points are
identical.)

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 exception
(as applicable) will be thrown.
