Which means: If humans have lives measured in millions of years, and a ship full of them set off on a 0.02C spaceflight to another planet that will take 100,000 years, it's possible that the crews perception of time can be sufficiently altered so that the flight only appears to take a few decades/years/months/days (we obviously don't know what the limits are). Time itself would continue to move at a speed relative to the velocity and destination of the spacecraft, but the perception of time could be so radically altered that the crew simply won't perceive it.
