This mod is designed to provide an automatic weather randomizer and day/night lighting mod. It only let's you enable it on the slate map currently, as that's the only one it's guaranteed to work on. The mod comes with a list of values that may be changed, but is already set up with an ideal set of values that look like this:

That's the afghan build, on slate, over the course of one clear day.
The length that each hour is in game may also be changed however it is by defualt set up that one minute irl is one hour in game, and thus, one day is 24 minutes irl.
I also said this randomizes weather, and it does.
Each day has a 50% chance of being overcast, as opposed to clear.
Each overcast day has a 50% chance of having precipitation. (it can not rain or snow on a clear day)
Each precipitating day may either by rain or snow, 50-50 chance either way.
There are three levels of density, "slightly", "moderate" and "heavily" each with a 33% chance.
This means that any one day has, for example, a 4.125% chance of raining heavily.
Also, a super admin, once the server is loaded and is running the slate map, must type "/startcycle" to get the lighting/weather going.
And anyone can type "/wh" to get stats on the time of day and weather in a nice, color coded, layout.
This mod has been tested extensively in my server, and if there are any suggestions for additions or complaints about bugs, don't hesitate to post them here.
I would recommend you use a build that covers the ground, as the ground turns the same color as the lighting by default, but if you're running any kind of rp, or a (t)dm then you'll be fine.

Okay, so in the server.cs (only script file) there will be these lines by default:

These set the default lighting values for each hour.
The function may be called at any time and contains 13 values.
The first is the hour, as you may see, the default has the functions lined up with the first value going from 0 to 23, as they should be.
The next three colors are the ambient/diffuse lighting.
The next three are the fog colors, this changes the color of the ground, and by default, is the same as the lighting.
The next three are the sky on an overcast day.
The next three are the sky on a clear day.
The amount of time between ingame hours, the amount of precipitation for "slight", "moderate", and "heavy" can be changed, and the chances of everything can also be changed fairly easily.
