Problem: A Discussion post displays the initial post date and when it was last edited. In April 2014, only one date and time is shown for the post. If the post is edited, that date and time will change from the initial posted date to the edited date.
Work around: None currently. An update is required to fix this issue, and we will need more down time to do this (ideally in the Summer)
For now, please be aware of the issue and limit the use of editing in Discussion Boards.
