How does the timeline finds the start and end date in plans?
One answer
I don't really understand the question and I also don't understand the background.
Given that, guessing, best I can say is: As far as I know you can't archive a Start Date. You can archive an iteration. If the iteration is archived it is flagged as such. This does not mean it is deleted, this only means it is not shown in user dialogs any longer. So the values are still there.
