Advanced Lienard-Wiechert potentials and fields?

  1. The standard (retarded) Liénard-Wiechert potentials and the expressions for the electric and magnetic fields derived from them are all evaluated at retarded time [itex]t_r = t - R(t_r)/c[/itex]:

    http://en.wikipedia.org/wiki/Liénard–Wiechert_potential

    Are the advanced Liénard-Wiechert potentials and field expressions exactly the same except that they are evaluated at advanced time [itex]t_a = t + R(t_a)/c[/itex]?
