Some say light does not age. I believe that it does experience time because it waves. Frequency endows the light wave with a clock if  its speed through space doesn't.

I happen to also to believe that light's clock is Gamma One or undilated time. It experiences no time slowdown like matter. Light's clock is the fastest.

It moves at the fastest speed in the universe in vacuo.
It waves at the fastest speed.
And its clock is the fastest in the universe.
