Solar angle on vulcan?

[RyuKajiya]

I wonder, is there something wonky with the solar angle readout of daylight sensor on vulcan?

Trying to automate growlight for greenhouse and from what I remeber from previous playthroughts the solar angle was best method to do that.
Think it was 0 at noon and goes to 180 at midnight, going down to 0 through the morning again. So usually did something like light on when angle is below 90.

But on vulcan it looks like the solar angle is all over the place. Had it at 110 during day. Going between 30 and 35 back and forth around noon and other strange stuff.
So basically useless for what I need.
Is that normal or a bug?

I know the black hole has variable orbit and compensated for that in solar panel controls. But can't figure out solar angle behavior so far.

An alternative is to measure the time with a Stop Watch from the Kit(music machines). This can also improve the plants growth efficiency, since the light and dark time can be fine tuned to better fit the type of plant being grown. Potatoes for example prefers 300 seconds of light and 200 seconds of dark, which is very hard to do with a Daylight Sensor.

The on/off state for the Grow Light can be toggled by MIPS or logic chips. When using logic chips build a circuit that calculates the following formula:
Grow Light "On" = (T mod (L+D)) - D
Where T=Stop Watch time, L+D=sum of Light and Dark in seconds, D=Dark in seconds.
This will need 2 i/o chips, 2 processor chips and 2 memory chips. The mod calculation can be found on the Processor Math chip.

The above formula will output a value with the range of -D up to +L. And since the "On" variable treats any number <1 as off, and >=1 as on, this value can be sent directly to the Grow Light. This makes the darkness 1 second longer and the light 1 second shorter than intended, but a small error like that can be ignored.

There are 2 things to keep in mind when using a Stop Watch
1) Sunlight can interfere with the darkness time, so don't use windows without shutters. Sunlight might also be able to pass through a roof made out of walls, so use a roof made out of frames to be safe.
2) The Stop Watch is also very sensitive, any changes to the cable network on its power-side will mess with the time keeping. So it's pretty much necessary to use an APC or Transformer to put the Stop Watch power cable on its own cable network to protect its time value.

I believe you have to make sure your daylight sensor is facing the correct direction.

I think it has to face to the north if memory serves.

Well.. not daylight sensor reading.. but Vulcan orbit itself. Its wired.
Black hole does not goes in the sky east->south->west, day&night length changes a LOT due to seasonal changes.. like 15+min day at summer and <5m day at winter, during winter its barely goes up over horizon.

Well I know that the orbit of the black hole is changing, but thought at least solar angle should be somewhat reliable to tell when it is nighjt and day.

I know the stopwatch method and have no problem making an IC10 clock too, but avoid that since both tend to be a bit dependant on game update loop and if base gets big they can lag behind making them not precise any more.
