Is Time Slower In Space

And for astronauts on the international space station.
Is time slower in space. For example time goes slower at the iss lagging approximately 0 01 seconds for every 12 earth months passed. Time dilation explains why two working clocks will report different times after different accelerations. And for astronauts on the international space station. If the observer is moving relative to the event then time changes by the theory of relativity but only between the event.
Time is not slower or faster in space. For gps satellites to work they must adjust for similar bending of spacetime to coordinate properly with systems on earth.
