Where did the time take place in Moby Dick?

Moby Dick starts with the narrator Ishmael setting out from Manhattan to New Bedford then Nantucket in Massachussetts. After setting sail from Nantucket, the Pequod travels across the atlantic, around the Cape of Good Hope, across the Indian ocean, and through the Southeast Asian Islands until it reaches the Pacific, where the novel ends. After setting sail, the ship never touches land, although Ishmael does describe some of his experiences off the baot.
