  In typical Josephson junctions, the Josephson current is an odd function of
the superconducting phase difference. Recently, diode effect in Josephson
junctions is observed in experiments wherein the maximum and the minimum values
of the Josephson current in the current-phase relation do not have the same
magnitude. We propose a superconductor-normal metal-superconductor (SNS)
junction where Josephson diode effect manifests when the normal metal region is
driven. Time reversal symmetry and inversion symmetry need to be broken in the
SNS junction for the diode effect to show up. We calculate long time averaged
current and show that the system exhibits diode effect for two configurations
of the driven SNS junction - one in which inversion symmetry is broken in the
undriven part of the Hamiltonian and the other wherein both the symmetries are
broken by the driving potential. In the latter configuration, a nonzero current
known as anomalous current appears at the junction in absence of phase bias. In
the proposed setup, the diode effect vanishes in the adiabatic limit.
