That's not an example of a distributed system, so it doesn't really clear up whatever the GP was trying to say about time in distributed systems at small scales.

But even if it was this is nonsensical. The visual content of a photo is generally not what is used to determine the moment in time when it was captured. There's metadata in the image format that specifies when the photo was taken.

There are pictures taken at almost the same moment in time all the time around the world, and there are many pictures taken of the same place, what's special about the situation here is that both of those things happened, and the subject isn't hyper famous, and it isn't a static object, so the chances of it happening were very low.
