I'd love to respond in great detail, but I'm travelling, so it's going to be criminally short.
One important factoid: while in special relativity the passage of time can only be specified for a given observer ssystem, the real world is somewhat different: the CMB gives us an absolute rest frame at each point. This allows absolute definitions of the passage of time, e.g. for the age of the universe.
A light beam has indeed no proper time passage in its own frame of reference system.
