The date when an episode was marked as watched

Hi, I would like to ask you a question, maybe you will be able to make this clear for me... One thing about the watchlist is a bit unclear to me... When I go to a drama's page, I can click on "Completed", then "History", and I can see when I marked each episode as watched - but in the "Timestamp" section it just says "one year ago", for example. Is there anywhere I can check the exact date? Thank you very much!
