In such a view, time is not emergent. It is, in fact, the only aspect of reality that cannot emerge from a more fundamental background. We register its reality, always and everywhere, by recognizing the differential character of change: some things change relative to other things. However, the kinds of things that there are also change, and so do the ways in which they change. That is what time is: the transformation of transformation.
