There’s no way to see all of that information at a glance, but if you hover your mouse over that “header area” for a few seconds, a little tooltip will appear with the full date & time that the change was made.
The “header area” is that area that says (for example): “You edited this record by modifying a field. 3 mo”.
If you’d like to see all of those full dates & times at a glance, you may want to add that as a product suggestion for the Airtable team in the #show-and-tell:product-suggestions category.
