Does maxwell equation means waves travelling from future to the present?

    restrocausality like the TI intepretation?

    Maxwell's equations don't change if we replace time by its negative. This doesn't imply
    retro-causality ; the speed of propogation is constant.

    Maxwell's equations are incomplete without boundary conditions.
    Causality is put in as a physical boundary condition in solving the wave equation.
    Advanced solutions are also useful mathematically, but not as the physical result.
