How to Change Day and Night Length in DayZ covers one of the most common DayZ server administration tasks.
This guide is written for PC DayZ server owners using a managed game panel, VPS, or dedicated server. Exact menu names vary by host, but the underlying DayZ files and concepts are the same.
Create a copy of the file, mission folder, profile configuration, or persistence data you are about to change. Keep a known-good rollback instead of troubleshooting from memory.
Time Acceleration
DayZ supports accelerated in-game time. Use the current Bohemia configuration reference for serverTimeAcceleration and serverNightTimeAcceleration. Test the actual day/night cycle because night acceleration multiplies the accelerated timeline.
