Ad Pruning Question

If I want to have a limited time special by increasing the ad duration from 30 days to 60, what will happen when I drop it back down to 30 after the special is over? Will the existing ads posted at the original 30 days expire at 30 days or 60? And will the new ads at 60 days expire in 60 days even after I drop the duration back down to 30?

Thanks!
Jeff
