Time doesn’t pass for a light particle, I don’t think. Just like Vonnegut’s Tralfamadorians, light “experiences” all its moments, everywhere it will ever go, at once.
I think this “inverted” way of thinking about time and space is the right one. We aren’t moving around in time — we’re moving with respect to fixed light cones in both space and time.
This way of thinking makes unparadoxical the constancy of light’s speed in all reference frames. Rigid space-marking rods are not the guideposts by which the universe is measured — timeless, spatially extended photons are.
UPDATE: Nice video rendering of photons by NASA. http://www.nasa.gov/multimedia/videogallery/index.html?media_id=154874171
