In theory, assuming humanity becomes a spacefaring race, how would age and time be handled across the planets? Is there a proposal for a unified system, or would these things be measured in respect to which planet you're located/living on?

It is said that the universe has no end, and is ever-expanding. But, assuming that we had a way to travel to (and possibly even beyond) the "edge" of the universe faster than it was expanding, what would we expect to be there? What would it look like? What would it even feel like?
