Member functions

(optional*)

(optional*)
Time point I/O
template < class Duration >

static std::chrono::sys_time < /*see below*/ >

    to_sys( const std::chrono::file_time <Duration> & t ) ;
(1) (since C++20)
(optional*)
template < class Duration >

static std::chrono::file_time < /*see below*/ >

    from_sys( const std::chrono::sys_time <Duration> & t ) ;
(2) (since C++20)
(optional*)
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
