  The CERN-OPERA experiment claims to have measured a one-way speed of
neutrinos that is apparently faster than the speed of light c. One-way speed
measurements such as these inevitably require a convention for the
synchronisation of clocks in non-inertial frames since the Earth is rotating.
We argue that the effect of the synchronisation convention is not properly
taken into account in the OPERA analysis and may well invalidate their
interpretation of superluminal neutrino velocity.
