  We study Ward identities for simple processes with external gauge bosons in
the time-ordered perturbation theory approach to time-like noncommutative gauge
theories. We demonstrate that these Ward identities cannot be satisfied when
all orders in the noncommutativity parameters theta_i0 are taken into account.
We conclude that in time-ordered perturbation theory one cannot solve the
unitarity problem of time-like noncommutative quantum field theories.
