Using a spatial gradient expansion, one may solve for the phase of the wavefunction by using a line-integral in superspace. Each contour of integration corresponds to a particular choice of time-hypersurface, and each yields the same answer. In this way, one can describe all time choices simultaneously. In an interesting application to cosmology, I compute large-angle microwave background anisotropies and the galaxy-galaxy correlation function associated with the scalar and tensor fluctuations of power-law inflation.8 pages, Latex 2.09, Fields Institute Publication: `Sixth Canadian Conference on General Relativity and Relativistic Astrophysics' Fredericton, Canada, May 25-27, 1995 One figure included in fileAstrophysicsGeneral Relativity and Quantum Cosmologytext
