Actually TAI depends a lot on relativity as well as quantum physics. For example, it is supposed to match the rate of the SI second on the geoid (which is roughly mean sea level). NIST's lab in Colorado is about a mile high, so they have to apply a general relativistic rate correction to their atomic clocks because of their gravitational potential. > so it should be good enough for most running code on the Internet.
