If you don't want to install an application, you could type something like

  pmset -g log|grep -e " Sleep  " -e " Wake  "

And get the same results (although a bit harder to sift through)

+1. Yup. Sleep is a 98MB wrapper around pmset. :)

Holy crap. The DMG is 33MB. What is being done that's so huge?
