To all, The new value here in decimals is : 10.9878 This is at JD 2339523.5, that is midnight at longitude 0 degrees. Planets gives at this time 10.9888 Dialist gives at this time 10.9883 To use for sundials these answers are all equal. The values in my previous messages were for noon at longitude 0 degrees. I should prefer to use the value at noon. The best will be the value at noon for the longitude the dial is calculated. What longitude this is? Fer J de Vries.
