Certainly; it's been measured. A few years ago someone took two atomic clocks and precisely synchronised them. One of them then "stayed at home", while the other was flown around the world in commercial airliners. When it came back, the clock that had been on its travels was a few nanoseconds behind the one that had stayed in the laboratory, even though they were still measuring time at precisely the same rate. The amount of time lost by the travelling clock was precisely in according with what relativity predicted.
