Revolution and rotation, specifically, have nothing to do with it, unless you're talking about time relative to the star it's orbiting around.
What matters is the planet's velocity relative to the Earth. Chances are, as the planet orbits (and as the Earth orbits), that relative velocity will
change dramatically...and, over time, it will probably approximately cancel out. This would lead to a net result of the same passage of time being
experienced on both the Earth and the other planet.
ETA: what would matter, in this case, is the relative velocity of the central star with respect to our Sun. That will give you the net relative
velocity of the other planet with respect to the Earth, and, from that, you can calculate the time dilation. According to us, they would be doing
things quicker because less time has passed for them relative to us. However, according to them, we would be doing things quicker, because, from their
perspective, less time would have passed for us relative to them. It all depends who you ask.
