I'm afraid that unless the Monolith is somewhere under Gran Sasso, those effects are completely negligible. The time scales of the experiment are very short indeed (1e-9 seconds), but the influence of General Relativity is even smaller (1e-15 seconds). The point to remember that there are so many possible factors that could mess up their results, that the error estimates that were published by the OPERA team were way too low.
