You could probably replace the usage of "time" with "increase in entropy", but it just makes it harder to understand WRT velocity. As your velocity increases, the entropy in the universe has increased as a result of whatever mechanism for acceleration is being used. If it's gas, then you are going from a nice, mostly orderly/low entropy liquid in a container, to a chaotic, high entropy gas that's now in the atmosphere.
