Order the entries by timestamp (or database id)

[JaneSjs]

          This is not related to the bug anymore, but I have a follow-up question (if it makes sense, I can also repost it as a new issue/suggestion):

Is it possible to order the entries by timestamp (or database id)? Alphabetic order of any field doesn't make much sense in our case (to track new registrations and send them confirmation emails). Looks like I would need to add the timestamp as a field in the survey or something to achieve that?
