Einstein predicted this in 1915, long before we had clocks precise enough to see it directly. In 1959, the Pound–Rebka experiment measured gravitational redshift in a laboratory, and later atomic clocks made the effect even more obvious.
Today, we have to account for it in GPS. Without relativity, your location would drift rapidly.
