If the game mechanics allow it to be done, and the game manufacturer does nothing to discourage it verbally (ie. announcing that it voids your warranty or whatnot) - then it is not cheating. They CAN announce later on that it's a bug they are finally addressing - but that's about all (aside from their fixing said bug via changes that prevent Time Travel from being accomplished any more).
