Are you trying to set the speed at which the sun rotates?
Are you looking for more realistic time?
Or are you trying to change how the clock increments?
It is hard to tell what you are trying to accomplish here.
If you are looking for realistic time I suggest also taking a look at the Sun Position Calculator built into Unreal. Here is a video that does something extremely similar using the SPC:
Any additional specifics and information you can provide will go a very long way in solving your problem!
For example, when the game starts It’s daytime. And the time during the day is 3 minutes. After 3 minutes has passed, it becomes night. And at night, there will be 7 minutes to turn into day. I had to make the time during the day shorter than at night. and keep looping like this, like a Day/Night cycle.
Sounds like you need Timelines. You can set up a Timelines for you day cycle and night cycle that loop into each other, or even one timeline that handles both if you set up your curve correctly. Check out the Unreal documentation here:
