Dan, What I mean is this:
1. Together with the sundial on the roof is given the EOT table. What can you do with it? As a result of the empirical way of construction on September 1 you can, using the EOT table, determine the standard Eastern European Time on other days. Specifying the length correction you could also determine the true local time 2. To indicate the standard Eastern European Time you have many options: clock, cell phone, computer ... There's no need to a sundial. Indicating the true local time is only possible on a sundial. Let him do it !
