As KM states, the TC can and does throw-off your boat's clock, and it can really mess with the cycles, but can take quite a while to be noticed. Bad Save data can also render "time of day" useless. However, there is a little thing called "
Base Time", and that is actually most of what you are mostly seeing, in that if you leave Pearl at 6am on December 10th (as an example), it is 1am December 11th (IDL intervenes) in Tokyo at that "time" in real life, so a 5 hour difference, plus the day added... In that Base Time link there, you might read that first post for the background story, and then advance to
Page Six, but be sure and ignore references to using Vertical Sync lock in the game's Graphic Options - that is NOT recommended any longer, as insinuated toward the bottom of the page when Front Runner got his new graphics card. Use of Vertical Sync on the 'modern' LCD display screen can and does cause "jello water", among other issues. Also, as Front Runner notes, Base Time and the "drift" encountered by not having the game's fps rate tied to the graphics card somewhere around the 30fps rate is only noticed at either consistent use of 1x TC or when using consistently high TC rates, as KM noted, from 1536x and higher, and generally only noticeable above 2048x TC on 'normal' length patrols. In Fall of the Rising Sun Ultimate v1.8, we do have "Time Zone" lines in yellow, and the IDL line in purple, but they are just artwork, and as such, not able to be easily "labeled" with "+10" or "-9" and the like, to ease the "math" needed for immediate sunrise and sunset calculations, but if you zoom out and count the lines, you can arrive at a good estimate by sight. Perhaps Bubbles will attempt to adapt that in his next version of TMO_BH, if he does one... Your comment of "... It get's light at 11:00 AM and dark at 11:00 PM..." would be about right, depending upon where you are along the coast line. The game does do Leap Years, but does not do DST, and does a rather poor job of latitudinal daylight versus night shifts, but is otherwise actually rather good at "time keeping" and star fields, so long as the "clock" is kept accurate, which is not easy to do, especially with the modern display stream of today's displays, cards and DirectX, and the game using the old DirectX v9.0c Libraries...
