I hope I understand you now. You want to edit the time that is displayed under the "Updated" column?
Using your example you want this. Your employee comes in at 8. Forgets to log in. You change that persons status at 10. But you want it to show that they changed their status to "IN" at 8 and not 10 when you changed it.
Currently you will have to do that in the actual database. It isn't too difficult to do, so long as you have MS Access I can give you a quick explination how to do so.
But to do it from the board I myself do not know any ASP so that would probably be up to David to incorporate that in his next releases. I would suppose that only the admins can change times, because you do not want your employees to "cheat" the times they logged in, if you were using it for a log of some sorts.
