🚀 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.

Frequently Asked Questions

Extended Time server crashes on startup – what to do?

Is Extended Time compatible with forge and neoforge?

Extended Time officially supports forge, neoforge for Minecraft 1.21.8, 1.21.4, 1.21.1. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Extended Time – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Extended Time consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
