Hey there @JikaiNoTsubasa! Welcome to the community!
So technically there’s many ways to make a clock, and it’s usually best to define the rotations by the clock and not the other way around, but in reality it doesn’t matter too much. Your implementation is perfectly fine! All you need is one little node and you can make the rotators read out 0 - 360!
The clamp axis node makes rotator readouts between 0 and 360 instead of -180 and 180.
This should allow you to just continue work on your system, let me know if you have any questions!
