That's not necessarily true, since we don't have proper physics to explain things happening at the speed of light. It's not possible to form a frame of reference for a photon. It has no detectable mass, and is traveling faster than c. We can't apply special relativity to a photon for those reasons. Our physics aren't complete enough yet. It might be better to say that at the speed of light, time in unable to yet be defined.
