Right, but doesn’t light travel at less than c in some situations (passing through glass, etc)? Would we say they experience “time” in those cases?

In these situation photons are either bouncing off matter or are getting absorbed and emitted by matter. In the former case they don't travel a straight path, in the latter case there is a short time lag between absorption and emission.
