Technically no. But it really depends on how they traveled from here to there, and back again.
If they followed the straight line idea and flew to their planet through space, there are limitations to how fast you can go and so on and so forth. If they used the wormhole theory, then they could get from here to there and back quickly, leaving the actual amount of time spent on their planet to be the main question.
Since this is alien technology we are really discussing here, there is no real plausible answer, as we are limited to what we know of our own limitations.
