Scientists at CERN say sent neutrinos arrived 60 nanoseconds sooner than they should have been able to. I'm skeptical of their saying that their experimental error is +/- 10 ns. That's not a whole lot more than a clock cycle for most fast processors, and how many combined processors does all their machinery have? Also, this:
the tricky part is accurately measuring the time between when the neutrinos are born by slamming a burst of protons into a solid target and when they actually reach the detector. That timing relies on the global positioning system, and the GPS measurements can have uncertainties of tens of nanoseconds.
