I've never heard of Timeliner. It doesn't have good Google ranking, so it was a bit buried. I think this is it:

  Timeliner is a personal data aggregation utility. 
  It collects all your digital things from pretty much 
  anywhere and stores them on your own computer, indexes
  them, and projects them onto a single, unified timeline.
