If you have two photons that have been emitted at different times, and no time passes at the frame of reference of the photon when they travel, what time is it when they interact?

In which frame of reference?
I think that's the detail underlying my question. Does the interaction collapse the frames of reference into one? I guess it doesn't have to.
The time of collision is not a problem, it happens at a different time depending on which photon's frame of reference we're talking about.
Which frame of reference the resulting particles might "inherit", well, that's a very interesting question that I've never thought about!
