  The wave equation and equations of covariantly-constant vector fields (CCVF)
in spaces with Weyl nonmetricity turn out to possess, in addition to the
canonical conformal-gauge, a gauge invariance of another type. On a Minkowski
metric background, the CCVF system alone allows us to pin down the Weyl
4-metricity vector, identified herein with the electromagnetic potential. The
fundamental solution is given by the ordinary Lienard-Wiechert field, in
particular, by the Coulomb distribution for a charge at rest. Unlike the
latter, however, the magnitude of charge is necessarily unity, "elementary",
and charges of opposite signs correspond to retarded and advanced potentials
respectively, thus establishing a direct connection between the
particle/antiparticle asymmetry and the "arrow of time".
