Finder does not sort correctly in mavericks

I have both 'sort by' and 'arrange by' sorted as last opened and still finder is not showing the files and folders correctly.

e.g., I have some documents made in 2014 but finder shows those documents as if they were made in 2013. Even 'last opened' shows them in 2013! I am pretty sure that the dates are correct because those documents are from my bank and they didn't exists at all in 2013.

When I put or open a file at a certain date in a sub-folder, why is the date last opened of the 'master-folder' not affected?

It doesn't update the folder opened date unless you open it in its own window. Just revealing it in a list view will not refresh the date.

Neither does adding a file to a folder refresh the opened date…
