The floors are ranked E, S and ★1, for the purpose of Treasure Boxes and Friend Rescues.
Floors 1 through 5 are medium-sized while 6 through 12 are large-sized; there will be 3 to 8 rooms on each floor. There are 1-4 items on each floor. There are 2-3 starting enemies on floors 1 through 5, and 2-4 on floors 6 through 12.
The IQ Booster activates on every even floor. The turn limit is 1000. The enemies in this dungeon have 26IQ, granting them the Status Checker IQ skill. There is water on floors 3, 5, 8, and 11. A sandstorm can be created on any floor by Steelix's Sandstorm, as well as by Hippowdon's Sand Stream from floor 4 onwards.
As noted by the dungeon's Japanese name, it is located on a hill. This can still be inferred from the English localization through the map of the future, as well as the mission objective seen in the dungeon menu.[1]
The full background used by the Passage of Time area includes a darkened line of trees in the distance, which remain entirely unseen in-game.
