template<class Duration> staticstd::chrono::utc_time</* see below */> to_utc(conststd::chrono::file_time<Duration>& t);	(1)	(since C++20) (optional*)
template<class Duration> staticstd::chrono::file_time</* see below */> from_utc(conststd::chrono::utc_time<Duration>& t);	(2)	(since C++20) (optional*)

1) Converts thefile_timet to autc_time representing the same point in time.

2) Converts theutc_timet to afile_time representing the same point in time.

The duration of the return type is computed fromDuration in an unspecified manner.

These function templates are optional: an implementation may choose to instead provideto_sys() andfrom_sys().

[edit]Return value

1) Autc_time representing the same point in time as the argument.

2) Afile_time representing the same point in time as the argument.

[edit]Notes

User code should usually usestd::chrono::clock_cast, which provides a generic interface to convert time points between clocks, rather than call these functions directly.
