Me too and found the answer in other blog. You should try this:
1. Open the file wp-document-revisions\includes\admin.php
2. Go to line 982
3. Change the or-statement ( || ) to an and-statement ( && )
The row should look like this when you’re ready:
if ( !isset( $old[0] ) && $old[0]->term_id == $_POST[‘workflow_state’] )
Ready, was resolved.
I modified the file admin.php on line 400, to show me the “post_date”.
In the “Revision Log” shows me how many days have been passed since the last update; but i want to show just the date
