std::chrono::file_clock::to_utc, std::chrono::file_clock::from_utc
template< class Duration >
static std::chrono::utc_time</* see below */>
to_utc( const std::chrono::file_time<Duration>& t );
| (1) | (since C++20) (optional*) |
template< class Duration >
static std::chrono::file_time</* see below */>
from_utc( const std::chrono::utc_time<Duration>& t );
| (2) | (since C++20) (optional*) |
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.
