If ultraviolet divergences in Feynman diagrams involve arbitrarily short time periods, approaching infinity, then can a finitist approach to time (assuming, perhaps, a limit to the time lengths that would avoid these divergences) possibly help to justify renormalization? Is there a clear reason why this would or would not be plausible?
