In this paper time-dependent solutions of supergravities with a dilaton and an arbitrary rank antisymmetric tensor field are found. Although the solutions are nonsupersymmetric the equations of motion can be integrated in a simple form. Such supergravity solutions are related to Euclidean or spacelike branes (S-branes).
