ok jim. just for you, and maybe a few others, here are the operating instructions for the sundial....
first and most important, determine which way is east.
second, point arrow in the direction that is east.
if the shadow is pointing away from the arrow, it's morning.
if the shadow is pointing to the arrow, it's evening.
if it is daytime, and there is no shadow, it's noon.
if it is night time, and there is no shadow, it's midnight.
so easy, even larry could use this sundial....
