This is PSA about superluminal neutrinos everybody was asking about, for those who are too lazy to look it up for themselves. Neutrinos supposedly pass 456 mi distance 60 ns (=18 meters) faster then light. The location of static points can be determined with 1cm precision with GPS. The actual location underground under the Gran Sasso mountain is determined with relatively poor 20 cm precision because it's not worth it to stop the traffic in the tunnel. Clocks at two location can be synchronized with under 1ns precision through the use of off-line "common mode GPS". Currently the largest source of uncertainty, and the most probable source of the error, is when exactly the neutrinos were produced at CERN. Gran Sasso is 100 mi South-East of Borgo Monastero Resort, through which the neutrino in question pass as we speak.
