NAME

std::chrono::file_clock::to_sys,std::chrono::file_clock::from_sys - std::chrono::file_clock::to_sys,std::chrono::file_clock::from_sys

Synopsis

template< class Duration >
(since C++20)
static std::chrono::sys_time</*see below*/> (1) (optional)

to_sys( const std::chrono::file_time<Duration>& t );
template< class Duration >
(since C++20)
static std::chrono::file_time</*see below*/> (2) (optional)

from_sys( const std::chrono::sys_time<Duration>& t );

1) Converts the file_time t to a sys_time representing the same point in time.
2) Converts the sys_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_utc and from_utc.

Return value

1) A sys_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.
