heal.abstract	We show that the ``time'' t_s defined via spin clusters in the Ising modelcoupled to 2d gravity leads to a fractal dimension d_h(s) = 6 of space-time atthe critical point, as advocated by Ishibashi and Kawai. In the unmagnetizedphase, however, this definition of Hausdorff dimension breaks down. Numericalmeasurements are consistent with these results. The same definition	en
