indeed, if we assume that time can be surpassed as a finite value ( of not a dimensional essence, or without any restricting boundary as the speed of light is) or it can be reversed in direction of manifestation in nature, or reversed in memory storage or retrieval by human beings, i.e. the way we remember and retrieve our memories, or man-made machines, eg. video reverse play, then it can be quantified and be depended on motion if you use the newtonian motion laws. these may sound physics of insanity but when we will be merging Virtual reality with Natural reality we will have to deal with such issues in medicine, in technology and eventually in everyday life...
