(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,
firstis filled out with the correct std::chrono::sys_info, andsecondis zero-initialized. - If the
local_timeis nonexistent, then result == local_info::nonexistent,firstis filled out with the std::chrono::sys_info that ends just prior to thelocal_time, andsecondis filled out with the std::chrono::sys_info that begins just after thelocal_time. - If the
local_timeis ambiguous, then result == local_info::ambiguous,firstis filled out with the std::chrono::sys_info that ends just after thelocal_time, andsecondis filled with the std::chrono::sys_info that starts just before thelocal_time.
This is a low-level data structure; typical conversions from local_time to sys_time will use it implicitly rather than explicitly.
