The length of days as well as years on the planet is logically not the same as on Earth: both seem to be much longer. After initially waking up on the planet, Royce notes to Isabelle that "the sun hasn't moved at all since we got here" several hours before and Isabelle uses a twig and leaf homemade compass in a puddle of liquid which only spins, proving there is no magnetic north on the planet. The nights on the planet are shorter than the days. The seasons of the planet are also long. Noland says that he has been on the planet for 10 "seasons", but he has been there since the Vietnam War 30 years ago. Therefore, roughly speaking a given "season" on the Game Preserve Planet may be three times as long as an Earth year.
