......I cannot get shadows to project on the ground, or even clearly on surfaces as I have seen in others' architectural models. All that happens as I slide time and date is a subtle variation in shading on surfaces until it blacks out. Any suggestions?
Where are your axes? See if reset is available if you right click on an axes in empty space. (Ground plane [R/G] for some reason could very well be 100m above your modeling space).
