The settings
- Day Cycle Speed: higher values make the whole day pass faster.
- Daytime Speed: how fast daytime passes, on top of the cycle speed. Lower values make days longer.
- Nighttime Speed: how fast night passes. Higher values make nights shorter.
Example
For long days and quick nights, set Daytime Speed to 0.5 and Nighttime Speed to 2.
On Linux
Add the lines to the GameUserSettings.ini card, for example DayTimeSpeedScale=0.5 and NightTimeSpeedScale=2.
Questions
How do I make nights shorter on my ARK server?
Raise Nighttime Speed on the World & Time card, for example to 2 for nights half as long.
