Modified column with seconds

Reference: Folder Format Manipulation Anomaly

My question doesn't actually have anything to do with the referenced topic, but is partly prompted by the images displayed in that topic.

How do I get a Modified column displaying date and time including seconds. The closest I've been able to come is date and time including hours and minutes only despite despite my system setting for Long Time being HH:mm:ss.

You can turn it on in -> settings -> preferences -> folders -> folder display -> show seconds in time column.

Indeed and "obviously" (now) I should have searched for "seconds" in preferences.
