Fyi, in the Users listing, people who are Invisible (such as myself currently), will have their Last Online value appear as "Invisible".  This seems different to our profiles where our Last Online value is blank instead.  However, if I'm logged in as myself and find my own entry under the Users listing, it will show the time I was last online in terms of minutes (e.g. < 1 min).  Not a concern for me, and I understand that its because different templates are used, but just thought I'd let you know.
