if there is an actual causal link between file A and B, the difference in timestamps should always be much larger than 100 ns.

And if there isn't a causal link, simultaneity is relative anyway. To Fred sitting at his computer, file A might have been created before file B, but to George running from the other end of the building in response to an urgent bug report, it could be the other way around.

So to be really accurate, the API needs a way for the caller to indicate a frame of reference.
