The photon actually experienced only one minute* and you one hour, that is what the clocks would show. The photon sees you one hour older and you see the photon

The photon actually experienced only one minute* and you one hour, that is what the clocks would show. The photon sees you one hour older and you see the photon one minute older.
It is like the waterplanet in the movie Interstellar (I think it was that planet), where they spent a short while on the surface and the person in space aged decades.
It is called time dilation [0] and there was a rather interesting experiment done by Hafel Keating [1].
* Interesting to know: time slows down to a halt at the speed of light, and the one second time lapse of the photon goes to zero no matter how long you wait on earth.
