std::chrono::local_info: std::chrono::local_info

NAME

std::chrono::local_info - std::chrono::local_info

Synopsis


Defined in header <chrono>
struct local_info; (since C++20)


The class local_info describes the result of converting a std::chrono::local_time to a std::chrono::sys_time.


* If the result of the conversion is unique, then result == local_info::unique, first is filled out with the correct std::chrono::sys_info, and second is zero-initialized.
* If the local_time is nonexistent, then result == local_info::nonexistent, first is filled out with the std::chrono::sys_info that ends just prior to the local_time, and second is filled out with the std::chrono::sys_info that begins just after the local_time.
* If the local_time is ambiguous, then result == local_info::ambiguous, first is filled out with the std::chrono::sys_info that ends just after the local_time, and second is filled with the std::chrono::sys_info that starts just before the local_time.


This is a low-level data structure; typical conversions from local_time to sys_time will use it implicitly rather than explicitly.
