There are two table columns in most tables, one ends in _LAD and the other in _LAT. The LAD is the last action date, and the LAT is the last action taken. Both are coded. The date is a form of a timestamp as the number of seconds since midnight on December 1970, and the LAT is coded as well. The documentation on the repository that we have posted in the Supervisor forum will probably help you understand what you are looking at.
