I have created two custom fields for posts – post owner and post assignee. I want to check the chain of possession throughout the existence of that post along with the timestamp. But, I’m unable to find a way to do so.

I checked into the WordPress post revisions but as far as my understanding, that doesn’t save meta fields out of the box.

I want to create a meta box in the post edit screen and display whoever was the owner/assignee of that post at a particular date and time.

Please help me find the possible ways to do so. Thank you.
