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.
