Word to the wise

I'll spoiler this just to be safe, but it was literally the first thing I thought to try when starting the game. Finally got around to trying it after like 20 hours, and I haven't seen it written anywhere else, so it might save some people some (real world) time:

! Nothing obvious happens if you leave the game open for three hours and "stay up all night" until after 8AM the following morning. The days don't even go up by two, so you technically travel back in time when the following day starts. I tried this in the den, which seemed like the most obvious candidate given its description. Still, feels weird that there's no interaction there. !<
