A couple of things: 1) Was it the lack of landscape or the incredible abundance of landscape that messed with his internal chronometer? Quite a lot of people would tell you of having spent hours in a mall and of having walked for miles and miles through its shopping aisles and quaintly-named corridors without having realized it.

And 2) can you design a landscape in which your sense of time is absurdly skewed, wherein you think you've spent an hour fumbling about in the dewy darkness but in actuality you were there for a whole week, perhaps a lot longer? Or vice-versa? The Super-Mall-of-America and the Super-Hospital-Waiting-Room.
