Time is not necessary for change to occur, I would argue. For example, how long does it take for a thought to disappear? I would argue it disappears in no time, or at least that it can do so. There isn't any transition period where only half a thought exists (what's the half of the thought "apple")? If we're talking about physical reality/matter, however, it must take time, because of the limits of the speed of light.
