When going to sleep with my flash new pillow and headphones on I would sometimes wake up with the music still blaring,  I wanted something that would tell my pc to shut down in x hours to conserve energy, and cut the noise off after giving myself enough time to go to sleep.  There are a few shutdown timers out there, but they are quite bloaty and annoying - turns out it was pretty easy to make my own here is how I did it (in windows XP). [:question:] are there similar functions for other OS :[question]:
