Our solar system is rotating within our galaxy, presumably you have to travel quite a bit before being „away from a gravity well“. But at that „location“, there may be a lot of relative velocity to our solar system, so there will be time dilation effects - for us or them, depending on your reference frame. ...One of the first things you learn in special relativity is that there are no preferred reference frames, I still have trouble wrapping my head around that one.
