std::chrono::local_info
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,firstis filled out with the correctstd::chrono::sys_info, andsecondis zero-initialized. - If the
local_timeis nonexistent, thenresult == local_info::nonexistent,firstis filled out with thestd::chrono::sys_infothat ends just prior to thelocal_time, andsecondis filled out with thestd::chrono::sys_infothat begins just after thelocal_time. - If the
local_timeis ambiguous, thenresult == local_info::ambiguous,firstis filled out with thestd::chrono::sys_infothat ends just after thelocal_time, andsecondis filled with thestd::chrono::sys_infothat 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.
