Current Time Lords:
The Graphic Ephemeris has the ability to show currently active time lords by clicking on the graph. You will need to set the option to do so in the time lords settings on the Reporting tab. This will bring up a window that looks like this:
This can be a rather long list or a relatively short one depending upon which time lord procedures you select. Right clicking in the white area brings up a popup menu with copy and paste / select all, cut, etc...
Time lords are listed in order from the most general (1) to the most specific (4) with their date of onset.
