modified time stamp

modified time stamp

I'm in updating potential records with notes. To keep them organized on the front page of the potentials section I have them sorted by "Modified Time". I was hoping that whenever I appended some notes to the record that the modified time would be updated to reflect when those notes were made and then the record would drop down and I would have the next record to manage. Unfortunately, that isn't happening. It looks like the "modified time" field keeps track of when the potential record was first created??
