Running 10.7.5, I've got a fairly new iMac (6 months old) 27", set to never sleep, yet when I got in to work this morning it was asleep. How to fix this?

Output from pmset -g in Terminal:

Active Profiles:
AC Power        -1*

And the contents of the com.apple.PowerManagement.plist in /Library/Preferences/SystemConfiguration:

As you can see, it has record of going to sleep this morning at 4:39 AM, yet all settings also show it's set to NOT go to sleep. Any ideas what's going on?

Do you perhaps have a schedule set to sleep the system? System Prefs > Energy Saver > Schedule button, or pmset -g sched (just sched).
