vanjast...I have done some limited testing and the the base time zone stuck. I need to do a whole sweep from West to East and East to West before I post the results.

The stars are definitely OK. The clocks can be fixed and made useful, either manually or through code à la reaper7. The sun will be covered in my next series of posts, after the clock tests, and the save game tests, and a demonstration of the map projection oddities.

I considered that map projection above, but rejected it. That one is still a Mercator and SH3 has none of the Mercator stretching of latitude at the poles. The devs gave us longitude stretching instead. Our map projection seems to be the most simple one of all.

This one in particular

That is why we need the "longitude shift" as Step 4 when plotting the 3 star fix, except when you are at latitude 0°. And the shift (actually a stretch) is the 1/cos or sec term. All will be revealed in the next voyage...hopefully.
