Hello
I found many tutorials how can I do day-night but I didn’t find how can I use OS’s time to change day-night cyrcle. I found many as increase numbers in float and so on…
I want so:
For example, if on my computer/windows/linux has 4 o’clock then in game shows 4 o’clock lights.
Thank you in advance for your response. 
Referring to the docs you can use FDateTime.Now() in c.
It’s not nativly in BPs afaik, but you can implement a c class which gives you a BP with the time. click
Thank you Speckulous your answer, but it is very hard level for me.
So I found this tutorial: Unreal Engine 4: How to Make a Day/Night Cycle! - YouTube and I made a little change in this.
I use this with Victory Plugin.
Here is my result.
