New conservative forms are introduced for time metrics and the Jacobian, which satisfy the geometric conservation law (:GCL) identity even when higher-order spatial discretization is employed for the moving and deforming meshes. The conservative quantities are ensured to keep constant for three-dimensional moving and deforming meshes with use of these new forms for the computation of the uniform flow. In addition, one of the new forms has spatial symmetry property, and some tests indicate the significance of the spatial symmetry in the expression of time metrics and the Jacobian.
