[REL] Nautical Almanac for 1941 - 1945

dmlavan · 01-29-08, 01:00 AM

I've created a Nautical Almanac for 1941 - 1945 to use w/ SH4. This document provides consolidated sunrise, sunset, moonrise, moonset, and moon phase information for the years 1941 through 1945.

The first page contains a map of the various time zones in the Western Pacific, as well as a legend for calculating local time. Since the time represented in SH4 is "base time", this legend provides the information necessary to convert from "base time" to local time. The remaining pages provide local sunrise/sunset and moonrise/moonset times for every day of each year, as well as the dates for the phases of the moon each year.

I have verified several dates at different locations and it seems to be fairly accurate. From extensive use of a similar chart in SH3, I know that the developers tried to get this aspect right.

Good stuff! I was really missing this info. They should have made a Captain's cabin for SHIV with this stuff printed on the calendar like they did in SHIII.

I know! I think Silent Hunter 4 is a great example of what might have been had the developers had the time...

That is true for all products manufactured, all software and all people. Every decision made or not made closes the doors on all possible alternatives.

(what's he smoking there, anyway?)

It would be cool to have this posted on the chart table or in a place instead of the pin up girls.

How dare you question the operational use of pinup girls.

Von Tonner · 01-30-08, 03:14 AM

Thanks dmlevan this is really great. Apart from the knowledge of knowing the sunrise and sunset times having the data on moon phases as well would help in night attacks. Good job

You're welcome !

The sunrise and sunset times are really pretty good. I was wondering why the sun was rising a wierd times.

What I can't figure out though is the time conversion map.
it states that if my base is Pearl and I am in Guam (zone I according to the map, Guam actually lays in the K time zone and not I) then add 19 hours to the base time to get the local time.

By my calculations, if you add 4 hours to Pearl time you get Guam time.

Thanks for providing the information though, it really helps.

dmlavan · 02-21-08, 10:52 AM

To go from Pearl time to anything on the other side of the International Date Line, you should add since it may be the next calendar date. However, since sunrise/sunset is not too different day-to-day, there's probably nothing wrong with doing the easier math.

M. Sarsfield · 02-21-08, 11:18 AM

I noticed that the moon phases are off in the game, though. When the moon should be new, for instance, it's actually a 3/4 moon (gibbous) in the game.

Schultzy · 02-21-08, 01:31 PM

Just adding my thanks for your work! It was sorely lacking!

Valkyrie · 02-22-08, 03:24 AM

Hi dmlavan,

I see where you are coming from on the time calculation.

Doh!

I must have had a really bad day and reversed my calculations.

Thanks again for the work.

dmlavan · 02-22-08, 10:54 AM

No worries - that darn International Date Line gets me too!
