MDY dates in CentOS article 

Hello there!  I've just  the date formatting edits, re-establishing MDY dates in CentOS article so, please allow me to explain it a bit further.  Manual of Style does say that existing date formats should be kept as-is, but before I came to edit that article, ISO dates prevailed and I've changed them to DMY dates.  Thus, I see no problems about moving this time to MDY dates, which, FWIW, I find to be much more readable.  Of course, I'm more than open to discussing this further. —  (talk | contribs)
