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.
