Sadly this is true.  To do it, we need a new format specifier, a new method in 
the date_facet, etc.  I'm thinking maybe %dd for the specifier?  And then 
you'd want a method to set the format like this:

    date_facet* df = new date_facet();
    df->date_duration_format("%-P%ddD");

where the %- controls the sign output.  Of course it could default to 
something like this.

Thoughts?
