You can get the duration from the context property timeSignatureFraction
or baseMoment:

%%%%%
\version "2.19.53"

{
  \time 12/8
  \applyContext
  #(lambda (context)
     (display (ly:context-property
                    context
                    'baseMoment)))
                    %'timeSignatureFraction)))
}
%%%%%

I don’t know how you can make a music function that uses this and
returns music. \applyContext #(lambda (context) (make-music …)) has no
visible output. But maybe it’s a start.
