The hat has a scanning laser in the brim. Orienting itself with an inbuilt compass, it displays the markings of a sundial on the ground around you, so that the shadow of your head indicates the time.

Head inclination angle would need to be monitored with respect to latitude and longitude, in addition to the compass function you speak of. All in all, a gloriously complicated and vastly less practical wrist watch alternative. Projected bun.
