Longitude:

Even without the aid of Celestial Navigation, the player can still navigate using Dead Reckoning to get to an Assumed Position within the sim, i.e., Distance in Nautical Miles = (Speed in knots x Time in minutes) / 60.

Make yourself a UT to Local Time Zone converter with whatever spreadsheet pgm you have. Its not hard to do. (Google: Time Zone Chart)

Van's Sun Almanac will work for SR & SS. These occurrances are based on when the sun is in the center of a time zone:

0-15-30-45-60-75-90-105-120-135-150-165-180 E/W. Each time zone is 15° wide, 7° 30' on each side of center.

You have to do the rudimentary simple math of adding or subtracting the time of SR or SS at your location from the center of the time zone of your assumed position based on van's sun almanac. If you're further west of the center of your assumed Time Zone, naturally, your SR or SS will be later. Depending if you are E or W of prime meridian and which side of time zone center determines whether you add or subtract.

You can also use the Sun Almanac to determine the Local Apparent Noon for the center of each time zone by subtracting SR from SS time, then divide the remainder in half, then add that half to SR to find LAN...then again, the rudimentary math as above.
When the sun is due N or S of your location, its noon.

In short, my advise is not to give up too soon on the mod. It needs a lot more eyes and players to do the testing.

Best of luck,
