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
,first
is filled out with the correctstd::chrono::sys_info
, andsecond
is zero-initialized. - If the
local_time
is nonexistent, thenresult == local_info::nonexistent
,first
is filled out with thestd::chrono::sys_info
that ends just prior to thelocal_time
, andsecond
is filled out with thestd::chrono::sys_info
that begins just after thelocal_time
. - If the
local_time
is ambiguous, thenresult == local_info::ambiguous
,first
is filled out with thestd::chrono::sys_info
that ends just after thelocal_time
, andsecond
is filled with thestd::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.
