There is no base time. In the point of view of the thing moving quickly away from us, OUR clocks are slower. For both of us, the other’s clock seems to tick slower. The situation is symmetric. This is why it’s called relativity, there is no objective static frame of reference And yes even if you were moving back and forth by one micron at close to the speed of light then an observer stationary relative to you would see your clock tick slower
