No, that isn't true. x amount of time passing on a spaceship, relative to an observer on the spaceship, would coincide with y amount of time passing on Earth, relative to an observer on the spaceship (whose measuring time e.g. by watching a clock on Earth). You're "fact" remains wrong because you aren't specifying the observer for the passage of time.
