Faster than light? CERN findings bewilder scientists

From the article:<p><pre><code> The scientists reached their conclusion after sending streams of tiny, subatomic particles called neutrinos hurtling from an accelerator at CERN outside Geneva to a detector at the Gran Sasso National Laboratory in Italy, about 450 miles away. "The neutrinos seemed to get there too soon — 60 nanoseconds too soon, give or take — than they should if they'd been traveling at the speed of light." </code></pre> So... How do these guys measure speed for something that is faster than light? If they start the stopwatch in Geneva, how do they know when the stuff arrived in Gran Sasso in order to stop it? The stuff used to communicate the arrival needs to travel at most at the speed of light, right? Are the neutrinos themselves the stopwatches somehow?<p>I guess physics is hard, let's go shopping!
