Over the years I have seen this image which always confused me:

"In special relativity, the observer measures events against an infinite latticework of synchronized clocks." This sounds needlessly artificial and abstract.

Let me take a stab at what they are trying to say. Say the event is a star exploding which is 1 billion light years away. The light reaches my eyeballs 1 billion years after the event happened. Therefore, one of these synchronized clocks mis-times the event. Do these clocks account for the time taken for the light from events to reach our eyeballs? 

**In the exact same frame**, I could have an observer 1 billion light years away right next to the star when it exploded registering a "more correct" time. 

So the observers disagree on the timing of the events, even though they are in the same frame? Or does the far-away observer back-calculate the time of the event, knowing the distance to the star, and then they agree?

**Now that I think about it, are all these clocks actually out of synch, but *appear* to be in synch by the time the light from all of them has reached the eyeballs of our observer?**
