DATE_FORMAT is currently using "EEE, d MMM yyyy kk:mm:ss z". If we really want RFC then should be using "EEE, dd MMM yyyy HH:mm:ss zzz". Otherwise should remove that comment. Anyway, I would think at least we don't want the hours from 1-24. Maybe make this one a 12 hour with am/pm? Note that this formatter is used for the footer and the locks, and differs from the last modified date formatter.
