About this Mod
Extended Time
Real-Time Day Cycles
Extended Time gives you total control over the duration of a Minecraft day. Whether you want a realistic 24-hour cycle, a 1-hour "long day," or a custom duration, this mod handles it with precision.
✅ SERVER-SIDE ONLY: This mod does not need to be installed on the client.
🚀 Features
Smooth Engine
Unlike basic commands that "skip" ticks, Extended Time uses a precise Accumulator Algorithm. It ensures the smoothest possible sun movement achievable server-side by calculating exact tick additions.
Capabilities
- Custom Duration: Set day length to any number of minutes.
- Real-Time Sync: Sync Minecraft sun with your actual server clock.
- Presets: Switch between 24h, 1h, 12h modes instantly.
- No Conflicts: Automatically handles
doDaylightCycle. - Persistent: Settings save automatically.
🕰️ Mechanics
Vanilla Minecraft runs on a 20-minute cycle. Extended Time decouples game time from tick rate.
| Setting | Effect |
|---|---|
| Vanilla | 20 minutes cycle. |
| 60 Minutes | Time passes 3x slower. |
| 1440 Minutes | 24 Hours Real-Time. |
| Sync | Sun position matches local clock. |
