Base Time 2018

OK, I understand what is going on when using the US Navy Almanac vs the SH4 game world. Looking at this (interactive) World Time Zone map.......

http://www.geoastro.de/astro/astroJS...e/worldmap.htm

(Navy Almanac for reference)
https://aa.usno.navy.mil/data/index

......you will notice that both Midway (X) and Pearl Harbor (W) are designated one time zone to the east of their actual, longitudinal, time zones!!
Longitudinally, Midway is actually in the (Y) time zone and Pearl Harbor is actually in the (X) time zone.

So, here we go again..... Midway is longitudinally -12 hours (or 12 hours West of GMT.) Pearl Harbor is longitudinally -11 hours (or 11 hours West of GMT.) This is why the US Navy Almanac works when you use the 11 hours West of GMT variable to verify your sunset time when leaving Pearl.

To determine Sunset time when based at Midway using the US Navy Almanac, you must use the variable 12 hours West of GMT. Even though Midway is listed as being in the 11 hours West of GMT for "official" time keeping purposes. That's why this is so confusing to us SH4 sailors. The SH4 game world is properly simulated longitudinally as far as celestial events are concerned as opposed to the somewhat arbitrary "time zones" assigned by "man".

In fact, when within 7.5 degrees longitude of 180 degrees (East or West of the Prime Meridian), you can use + or - 12 hours and arrive at the same time. For Instance, Fiji is 12 hours East (+12) at 178 degrees east longitude and Midway is 12 hours West (-12) at 177 degrees west. On the Midway side of the line it is today, on the Fiji side of the line, it is tomorrow.

Just remember, when you are based out of Pearl, or Midway, and you travel West of the IDL, your Base time is what time it is at Midway, or Pearl, and the date is yesterday.

I know this has been discussed at length many times before. It has always confused me.

Now I understand the math behind it. The SH4 team made very good decisions concerning "Base time." It is up to us, the player, to understand the mechanics behind it all.

From Wikipedia.....

"Since the 1920s a nautical standard time system has been in operation for ships on the high seas. Nautical time zones are an ideal form of the terrestrial time zone system. Under the system, a time change of one hour is required for each change of longitude by 15°. The 15° gore that is offset from GMT or UT1 (not UTC) by twelve hours is bisected by the nautical date line into two 7.5° gores that differ from GMT by ±12 hours. A nautical date line is implied but not explicitly drawn on time zone maps. It follows the 180th meridian except where it is interrupted by territorial waters adjacent to land, forming gaps: it is a pole-to-pole dashed line."

Funny thing is, in all of the books I've been reading, at the beginning of the war, Pearl Harbor was 30 minutes behind (or ahead - take your almanac pick), of everybody else. Trying to be precise I guess with their sunrise & sunset times...

So, Florida has passed legislation, that would make Florida, the first and only State to go on permanent Daylight Savings Time. Congress has to approve before it can go into effect. We would always be -6 hours West of GMT no matter winter or summer which would mean that although our winter solstice sunset would occur an hour later, 1842 instead of 1742, our winter solstice sunrise would also occur an hour later, 0817 instead of 0717. Everyone will be driving to work and going to school, waiting for the bus, in the dark. Can you imagine the wintertime airline schedule confusion?

I'm against it!

Permanent Standard time (-5) hours is preferable IMHO.

We used to have permanent Eastern Standard Time in most of Indiana, which I liked. We're mostly in the middle of the Eastern and Central zones anyway, so why not? You always knew when sunrise and sunset were, and the day seemed "normal", as far as daylight went. But they had to meddle with Mother Nature, and now we have "Daylight Savings Time" (what is "Saved", I'd like to know). Now an old man can't get to sleep during the summer for the sunlight at 2200 hours... I'm moving to Alaska!...

What is saved? Why daylight, of course. (But only a bureaucrat could explain how this is done.)

[Jeff-Groves]

I'd like to know where all that daylight I saved went when Spring comes around!


Is someone stealing it and putting it in a daylight savings account somewhere?

It is being distributed to people who don't have as much daylight as you do.

It's as confusing as Base time

So what are the practical results of this impressive investigation?

• Don't load save games from in-game
• Enable vertical synchronization
• Limit refresh rate to 30 FPS

Am I missing anything?

The save/load game issue was isolated to FOTRSU and has mostly been solved. It was in game patrol start date related. I could not produce the error in TMO and Vanilla. Best practice is to not save game over a previous save game.

V-Sync = ON

Using Nvidia Profile Inpspector, set the Vertical Sync to "1/2 Refresh Rate" to preserve celestial sphere synchronization with gameplay at 1x. This is not a major issue if you mostly play at accelerated game speeds, this issue only affects the game while you are in 1x time, so, to some minor degree it affects everyone who plays it. I discovered it because I was using the game as a "screen saver" and played at 1x for "days" at a time. I also like listening to Fred's Radios.
