More specifically printAlbumDate() uses getAlbumDate() which uses zpFormattedDate() which uses the php function strftime()
So [b]use the formatting specified on this page: http://php.net/manual/en/function.strftime.php [/b]
In your example it's printAlbumDate("","","%a %d %b %G")
printAlbumDate DOES NOT uses the php date() function that you're probably familiar with which is why "D d M Y" won't work.
