That is an interesting way of thinking about it markosr; but this view has some serious flaws.
The speed of light is very much a finite speed. That's how we can use lasers to measure distances (or times w/ a known distance); that's why gravity/electromagnetism doesn't respond instantly, and thus why waves are able to exist in both cases.
Additionally, while it is a tempting question, there is no valid reference frame traveling at the speed of light---thus you cannot ask
what 'time durations' are for such an observer.
