Well, if you think about a fisheye type lens (usually smaller than 28mm) it will affect the appearent distance from the sun to the horizon. I'm just throwing things out there since I don't have your scene on my system. Also, verify if you have DST selected or not and make sure it matches time zone settings, plus distance from the time zone edge. If you are in the middle of the time zone, it might affect it too.Originally Posted by Mr Cory
