Hi, to calculate the eot I made a little R-programm, you find the code (and a fancy chart) at http://commons.wikimedia.org/wiki/Image:Zeitgleichung.png you can easily change the constant kappa=0.016722 to 0.0172 if you have any quastions concering the code, read the linked paper or feel free to post you question on the discussionpage or here.
