Dear Membership, In some current sundial projects the ability to correct for Longitude, Equation of Time and Daylight Savings Time had to be incorporated. In some of these the idea of rotating the dial about the gnomon axis would work but others were too cumbersome to even contemplate doing this. Some thought led to the concept that any dial can be compensated/corrected by rotating it around Any axis parallel to the gnomon!! Since rotation about the actual earth's axis works and also around the gnomon axis, this should work. Trial on a few models shows that it works. Of course you all probably know this already, but the idea was new to me. In one model I tilted the pedestal at it's base the required degree about an axis, in another I shimmed up the dial plate on one edge, another works well with a hinge. What a joyful degree of freedom!
