Considered from the frame of reference of the photon its transit _is_ considered to take zero time. This is the so-called _proper_ time. Improper time is the time measured by some observer in another frame moving at some speed less than c (e.g. the experimenters). This improper time varies from frame to frame but is always more than zero. More formally, the photon track is regarded as a null signal line, a line between point events A and B on which the invariant relativistic called _interval_ is zero. This is called a space- like interval. All observers in all inertial frames will agree on the value of it, although they will disagree about the improper spacetime separation of A and B depending on their relative velocities. The CERN result implies (or is believed to possibly imply) that in the _proper_ time frame of the neutrinos they made the trip in less than zero time (i.e., in imaginary time), and so _would_have_ arrived "before they departed". This is exactly why the result is facing such a strong challenge. Martin Shough Listen to 'Strange Days...
