Kudos Given Timestamp?

I'm using the method "/kudos/givers" of the "Message" class, and the response does not include the timestamp of each of the Kudos given. (The date the Kudos was given is configured to show on website's leaderboard, so I'm guessing the timestamp is available stored in the backend, just not yet exposed on the API response.) Is it possible to retrieve the timestamp the kudos was given, or include it as a mixin of the response of the "/kudos/givers" method? Thanks in advance!

As an example, here's a screenshot showing the time Kudos were given for the top Kudoed idea on the Lithosphere:
