🌦️ Features

  • 🕐 1:1 Real-Time Synchronization
    Your Minecraft world ticks forward in real-time—1 second IRL = 1 second in-game. No more accelerated sunrises or rushed nights.

  • 🌍 Custom Yearly Calendar

    • 28-day year divided into 4 seasons

    • Seasonal transitions bring new visuals and effects (WIP)

    • Dynamic moon phases

  • 🌬️ Custom Weather Engine (WIP)
    Realistic weather progression independent of Minecraft’s default system:

    • Wind mechanics (Planned)

    • Localized storms (Planned)

    • Temperature-based weather changes (Concept phase)

  • 📻 Dynamic News and Alerts System
    A trigger-based interface displays contextual updates such as:

    • Current time of day

    • Moon phase

    • Season

    • Biome (WIP)

    • Wind conditions (WIP)

    • Active world events or warnings (e.g., approaching storms)

🛠️ Setup Instructions

To set up Realistic Time in your world:

  1. Install the datapack as usual in your world save folder.

  2. Run the following command once:

    /function realistic_time:calibrate
    

    This will initialize the system and set the world time to 6:00 AM.

⚠️ Important:
Do not use /time set or other /time commands after setup. This will break synchronization.
