Compound time signature

[Thomas Scharkowski]

Hi,

  I try to print a compound time signature using this construction:

--
\once \override Staff.TimeSignature #'stencil = #ly:text-interface::print
   \once \override Staff.TimeSignature #'text =
   \markup {
     \override #'( baseline-skip . 0 )
  %%%   \hspace #2
     \number {
       \center-column {\line {"3 2 3" } "8" }
     }
   }
--

The first number touches the clef, so I used \hspace to shift it to the 
right - but then the 8 jumps down one space.
Any hints appreciated.

Thomas
