std::chrono::file_clock::to_utc,std::chrono::file_clock::from_utc(3) | C++ Standard Libary | std::chrono::file_clock::to_utc,std::chrono::file_clock::from_utc(3) |
NAME¶
std::chrono::file_clock::to_utc,std::chrono::file_clock::from_utc - std::chrono::file_clock::to_utc,std::chrono::file_clock::from_utc
Synopsis¶
template< class Duration >
(since C++20)
static std::chrono::utc_time</*see below*/> (1) (optional)
to_utc( const std::chrono::file_time<Duration>& t );
template < class Duration >
(since C++20)
static std::chrono::file_time</*see below*/> (2) (optional)
from_utc( const std::chrono::utc_time<Duration>& t );
1) Converts the file_time t to a utc_time representing the same point in
time.
2) Converts the utc_time t to a file_time representing the same point in
time.
The duration of the return type is computed from Duration in an unspecified
manner.
These function templates are optional: an implementation may choose to
instead
provide to_sys and from_sys.
Return value¶
1) A utc_time representing the same point in time as the
argument.
2) A file_time representing the same point in time as the argument.
Notes¶
User code should usually use std::chrono::clock_cast, which
provides a generic
interface to convert time points between clocks, rather than call these
functions
directly.
