Actually, FILETIME is a structure, the function just optimises its operation by converting it to uint64_t internally, which may not be valid on Linux. Obviously, this structure is not available on Linux, so there's no way you can acquire it from OS.
The from_ftime function (and all other facilities it uses) are targeted for Windows platform and operate on FILETIME, not on some opaque uint64_t. FILETIME has additional value semantics, such as the base date and resolution. These semantics are not described for Linux.
I agree, but the point is that semantically a FILETIME is defined as "an opaque structure representing the number of 100-nanosecond intervals since January 1, 1601". Integer types are perfectly capable of representing exactly the same semantic definition, so why not? I don't think it even requires any code changes except to remove a single #ifdef in the date_time header files.
