I just had a discussion with @huixie90 about this. We both agree that the spec should explicitly take these `time_point`s by value instead of by reference. Hui will file a LWG issue about it. I would like to do this and consider it a DR -- it's not an ABI break for us and it seems like the simplest and most self-documenting way to handle this. CC @jwakely

Let's wait until we have a LWG issue and see whether there's appetite for moving to by-value.
