std::chrono::file_clock
Member functions
file_clock::to_sysfile_clock::from_sys
(optional*)
(optional*)
Time point I/O
template< class Duration >
(1)
(since C++20) static std::chrono::sys_time </*see below*/>
(optional*)
template< class Duration >
(2)
(since C++20) static std::chrono::file_time </*see below*/>
(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().
Contents
[edit] 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.[edit] 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.
