Need help with an older day night cycle bp

Hi, anyone create the tutorial series from kleiner bears complex day and night cycle?
That’s while my old HD is destroyed could not save them, and the core blueprints are gone.
I have the most reconstruct, but i don’t remember how i implemented the gametime change to systemtime, thats the sun and moon turns at that time exactly.
Would be very grateful when someone can send me pictures here in the forum from that.
Here is a picture of the event graph:

Solved by my own, all works perfectly for now.
