Would there be a way to make the ingame clock go with the same speed as the real clock? There is a really bad shadow bug associated with shadows adjusting to the sun position and slowing down ingame time would make it way better.

Better question: Is there a way to slow down the out-of-game clock so I can play more?

You don't need a mod at all. Just use the console.

set timescale to #

where "#" is whatever value you want. I use 8, but you might want something else.

You can also put this in a batch file and run the file from the console. For example, if you put tthe command in a file called "init.txt" and start the game, you can open the console and run it:

bat init

and the console will run the batch file named "init.txt"
