> I think that should be documented on the public API part with a mention that the resolution is expected to differ depending on the file system and OS. WDYT?

That is a good idea, the way I consider `file_status` is that it provides a cross-platform way to get at the file properties. It provides times in nanoseconds but leaves the precision as implementation detail of the underlying file system, which makes sense, people should not expect anything more than that.
I'll add some comments.
