"Just a brief note to let you know that my Mum and Dad were absolutely delighted with the sundial. My dad is a recently retired precision engineer, having spent fifty years in machine shops working all kinds of metal. He could see the high level of workmanship that you had put in to the design and manufacture of the dial. He has been reading the installation instructions and we will send you through a picture once the dial is installed.
Thank you again for all your hard work."

Armillary Spheres are set to show “Local apparent time” This is when it is said to be noon when the sun is directly overhead. ( Its highest point in the sky when directly above the position of the viewer.) Time as it used to be before Greenwich mean time was introduced to standardise time across the country- thus allowing railway timetables to be aggregated.
The “Greenwich Time adjustment” EOT plate shows the seasonal adjustment of dial slow / dial fast, together with an adjustment for the dial’s position East or West of the Greenwich Meridian. If the dial is correctly aligned to solar noon (local apparent time) it will then be possible to ascertain correct Greenwich mean time.(Standardised time)
