In Jimmy Olsen #28, Jimmy gets caught in a whirlwind that Superman created to stop a hurricane from hitting Metropolis, and is transported to the Metropolis of 5921. He is startled to learn that he is reviled as the man who killed Superman, way back in 1958 (when the story was published). He is arrested, but hopes to get off as there are surely no witnesses who can attest to his identity.
We learn at the end of the story that Jimmy's murder of the Man of Steel was actually faked; it was all a ruse that Superman had come up with to trick a gang. Later, Superman hurls a time capsule into the future to clear Jimmy's good name.
