Before jumping in and changing it, would there be any problem in 
modifying all those DublinCore methods that currently call the 
ISO-method on the DateTime class to return a correct ISO 
8601-representation instead? Here's an example:

October 13th, 2004 at 2:34:54 PM in Fredericksburg/VA (EST)

ISO returns: 2004-10-13 14:24:54
ISO 8601 should be: 2004-10-13T14:24:54-05:00
