  We show that an isolated impurity in a spin singlet d_{x2-y2} superconductor
generates a d_{xy} order parameter with locally broken time-reversal symmetry.
The origin of this effect is a coupling between the d_{x2-y2} and the d_{xy}
order parameter induced by spin-orbit scattering off the impurity. The
signature of locally broken time-reversal symmetry is an induced orbital charge
current near the impurity, which generates a localized magnetic field in the
vicinity of the impurity. We present a microscopic theory for the impurity
induced d_{xy} component, discuss its spatial structure as well as the pattern
of induced current and local magnetic field near the localized impurity spin.
