I thought it was widely agreed that time was a construct?
It has been a common belief in philosophical circles for centuries, but not among physicists. Both Newton and Einstein thought of time as being one of the fundamental properties of the physical universe.
However, in the past decade or two, some theoretical physicists have now come back around to the idea that space and time could instead be emergent properties of a deeper, underlying reality.
If you really want to go cross-eyed, read up on the holographic principle.
My favorite theory is that time and space are reversed in a black hole which could be at the beginning and the end of the universe.
