The confusion is between proper and improper time. 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.
