Plutarch has made a similar observation on the importance of that universal limitation on our thought and action: time is, as they say, of the essence!
13: So the buildings arose, as imposing in their sheer size as they were inimitable in the grace of their outlines, since the artists strove to excel themselves in the beauty of their workmanship. And yet the most wonderful thing about them was the speed with which they were completed. Each of them, men supposed, would take many generations to build, but in fact the entire project was carried through in the high summer of one man's administration....It is this, above all, which makes Pericles' works an object of wonder to us -- the fact that they were created in so short a span, and yet for all time.
The point being that mixing process and time says something about the doer: complex process, plus short time = wonder at the outcome. Any process and huge time: not remarkable at all; thus the brief time of God's creating is an important part of the Genesis record, I suggest.
