Rob, I believe 'time varying fields' is not the only condition. To bring displacement current into play, the other condition is the geometry of structure(incl. material). Let us consider two mundane examples: 1) ordinary light bulb, and 2) florescent(tube light) bulb - both excited by time varying fields. How would you explain displacement current in each case?
