Hello, I'd really want the clock to be in the right time zone, eastern time, because I'm in Cape Canaveral. Right now, the Sun is rising at midday, because the actual time zone is GMT... I can't find a way to do this. Worst, I deleted an older game save, where I was able to achieve this time zone fix correctly at start, and for the life of me, I can't remember how I did it. If anyone could help me with this, I would be so grateful.
