Reminds me of a SF story, in which a traveler is stranded X light years from Earth, X years after the start of WWII. It takes a while for the rescuers to arrive, so to fill his time, he's listening to radio broadcasts and tracking the progress of the war in real time. When help arrives, he almost insists on being allowed to remain, so he can hear how it turns out, before he comes to his senses.

Smaller scale but similar idea.
