Time works a little oddly in this game. There seems to be no passage of time unless you want it to pass, and there's no clock on your cell phone. There are some timed puzzles, but as at Alice's tea party, it's always 4 o'clock (or whatever).

You can, however, change the time from day to night and night to day. To do that, go to your bedroom (in the lounge), which shows what it looks like outside. (Your cell phone also shows you whether it's day or night.) Click on the sun to go to daytime and on the blue thing that looks like a raindrop to go to nighttime. It will then stay that way until you click to change it again.
