So, I seem to be able to set a shutdown time... but I'm not sure why it doesn't shut down?

Edit: Well, it looks like if I power it off by hand using the touch sensor, the wake timer seems to work, which is nice :)

Do I need to have the device plugged in and then disconnect it for the auto shutdown timer to work?

Edit 2: Actually... once the device booted back up, it shut down after a minute.... That was weird...

Please refer to the product brief for details on each of the register settings. The AUTO_SHDN_TIME sets the time after which the Pi will be shut down when external power (VIN) is removed. It's intended (in combination with AUTO_BOOT 3 or 4) for automatic boot and clean shutdown based on the availability of incoming power (think clean shutdown for a device with a hard on/off switch cutting power). Your Edit 2 seems to indicate it's working as intended. You had set the time to 1 minute and must not have had the unit plugged in at the time?
