Some of our displays are evolving frequently and consumers of the displays would like to know when the current display they are viewing was last modified. It would also be a nice bonus to be able to display the creation date of the display also.
I would not know of a standard way to do this using supported methods.
I would recommend to include this as a plain text on each display and update that on every change/release of a new display.
This information is already available in the database, so it is a question of how to get it to the client. As Roger said, there is no standard way to do this. I would suggest making a suggestion on the feedback site. I could see something like an 'i' icon on the thumbnail that would show more details, or else enhance the hover tooltip to include this information.
