Time Shifting

I've read the short tutorial on Girder. And I can't seem to find this:
I want Girder to turn on my [anything][or in my case, my stereo receiver] at a certain time of day. My idea is to control my receiver, so that my computer can record music/programs while I am at work.
Can anyone point me in the right direction to learn about time, time shifting, etc.?
