I've found that by adding or subtracting hours to my 'ships clock' (which is using base time ) depending on my distance from base, the tables available on the internet for Sunrise & Sunset, Moonrise & Moonset, and the Moon phases are very close to what I see in SH4.

Unlike real life, Latitude doesn't seem to be factored in, but longitude is, which is why knowing what time it is where I am is useful; base time + 5 hours for example.

This information is so helpful that I added the tables for the Sun & Moon and the moon phases to my in-game F1 Help file, for use in planning my attacks, recons, whatever.

I begin each patrol by drawing vertical lines for each time zone on my chart. No, I don't include the jogs that some real time zones have, but I start at the 180d date line which is in the center of its time zone, draw two lines on each side 7.5d to the East and West, then every 15d from those lines. Each of those lines is one hour.

I made this into a mod for a friend years ago. Editing the in-game F1 Help file to include useful information is helpful : ) Ha!

Happy Hunting!
