I have a mini that I use for a HTPC, and half the time when I go to wake it up, it's already awake. I'd like to find out what's causing it to wake up spontaneously, and the first step is a timeline. So does anyone know of a way to find out what time(s) a mac awoke from sleep? Thanks

Check the system.log in Console.

I don't see anything there. Was that just a guess or did you have something in mind?

No, it was not a guess. The time it goes to sleep and the time it wakes up is recorded in the system.log.

This is from mine this afternoon. You can see references to going to sleep and waking up.

You can try this in the terminal:
cat /var/log/system.log | grep "System Wake"
