Per an Einsteinian viewpoint, they could be the same thing. Einstein basically labeled the creating force "God" without characterizing it as any specific person, place, force, or thing(s); saying, "I don't really know yet what the creating force is; that's what science is all about."
Ok, so God is defined as "transcendent", but Time (in substitution of God) can't be transcendent, otherwise it could not possibly be subject to science...
