Depends. Were you to sit on the photon. Your watch is stopped. Were you see the photon
as it left the surface of the Sun via reflection (initial time) and to travel on it's original
path to the Earth. You could then signal to a partner (in communication with) on the
Earth, who would capture that said photon -- yes, 8 minutes later.
The difference is Special Relativity (SR). It depends where you are in the observation.
