Adding date/time to leaderboard entry

I would like to be able to add a date and possibly timestamp to leaderboard entries.
My game is for helping guitar students learn chords and currently there are a few people who do really well and have several top entry slots but we find we would like to know what score was done when.
I see in the dashboard I can see the date but don’t see a way to add it in to the leaderboard the students can see


Good luck on your project.
