I think we can. But since there is more than a minutes error accumulated during a person's lifetime, I am glad someone is doing this. I am fascinated by the fact that they *can* do this. I would assume that this requires rough agreement (a few milliseconds difference) between measurements made at different observatories. These are on different plates of this earth, and these plates are drifting, earthquakes are moving the observatories, and so on. . GPS is not an answer, it intrinsically has the same problems.
