“For example, noon on a sundial in Cambridge, which is an eighth of a degree 
east of Greenwich, is 30 seconds earlier that on a sundial in Greenwich. To 
adjust for this, the angle of the gnomon has to be calibrated to that of the 
local area.”

Strange.

I always thought the gnomon angle adjusted for latitude, not longitude. No 
wonder none of my dials show ‘clock time’!

Still, it is the Daily Fail!
