We've updated the edit history page to show which user performed an edit. This should make it easier for teams to keep track of which changes were made by whom. If you still want to view the time that a scheduled to be undone at, you can do so from the 'Scheduled edits' tab of the history page.
It's also possible to see who performed an edit while looking at the edit detail page. Just click on More actions → View configuration and scroll down to the bottom of the popup window.
