Blimey, I think I'll stick to sundials, I can understand them, I suggest
Airy does the same.

Actually, sun dials are an interesting topic in their own right. There is
a
"sundial society"- not sure of the correct name but a local SK was a
member
and made sundials to plans he got from them.

I found an interesting article on the web about sundials, and one particular
manufacturer who claimed that, provided you followed their installation
instructions precisely, their sundial could be read to an accuracy of one
minute!
ISTR they calculated the rotation and tilt from your latitude / longitude.
No Summer Time correction, of course, and not much use at night, unless you
use a torch!
