std::chrono::local_info
From cppreference.com
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, andsecond
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 thelocal_time
, andsecond
is filled out with the std::chrono::sys_info that begins just after thelocal_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 thelocal_time
, andsecond
is 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.
