Superman-Tim #[61]

Tim knew that the vikings were brave enough to cross the ocean in the year 1000, but he had to see for himself. Using the whirlaway watch, invented by Superman, he travels back over 900 years. Tim arrives on a viking ship and warns the crew of an approaching waterspout. After the trouble is avoided, Tim is told that they are now heading into the Sea of the Serpent, towards the land they call Vineland. During a storm, Tim is swept overboard. One of the vikings jumps in after him, but both drift far from the ship. They climb onto a small island, but it turns out to be the back of an angry whale.
