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.
