Interestingly, it depends on your altitude. For objects in a low, fast orbit such as the ISS, time runs slower; in higher, slower orbits, such as GPS and geostationary communications satellites, time runs faster. In between these points, the effects cancel out at an altitude of roughly 3000km.
However, both effects can be ignored for almost all purposes. The effect of time dilation is less than 1 part per billion, which is basically undetectable without an atomic clock.
