Weather Report?

"...I have been to japan before, and in fact, i live in beijing now. i know for certain the sun does not rise at 11 am in this part of the world. how come in the game, it does? not that i mind a little more darkness, but..."

3033 is correct. If you hold your mouse over the time in the lower right, you will see the words "base time." This is no different than SH3 which was also a fixed time of GMT with no zone compensation. Where I live, the sun is going down @ 04:00 GMT. For those based in far east ports, the time difference is a lot less for them than for us Pearl folks, but they also get kicked out of their bases early in the war.

I also use 3033's same suggestion to mentally or on a bit of paper "mark" the time I see the map color change while time surfing. I use that to judge when I should be hiding and attacking in enemy controlled water. Historically, dusk and dawn (the two hours around those times) are the most ideal for subs, but I don't let that keep me from attacking at all hours if other conditions are favorable (weather, no escorts, few planes spotted recently, strong battery, etc.)
