RealtimeSynth
RealtimeSynth synchronizes your real-world time with Minecraft's day-night cycle, creating an immersive experience where the game world reflects the actual time of day. Perfect for players who want their Minecraft adventures to match the rhythm of real life!
Features
Real-Time Synchronization: Your Minecraft world time automatically matches your system clock
Seamless World Creation: New worlds spawn with the correct time of day based on when you create them
Automatic Updates: Time syncs every 10 seconds without any performance impact
Smart Mapping: 6:00 AM real time = sunrise in-game, 12:00 PM = noon, 6:00 PM = sunset, 12:00 AM = midnight
Configurable Notifications: Toggle sync messages on/off to your preference
Time Display Commands: Check both real and in-game time with simple commands
Server Compatible: Works perfectly on both singleplayer and multiplayer servers
How It Works
Once installed, RealtimeSynth runs completely automatically in the background. The mod disables Minecraft's default day-night cycle and takes full control of time progression based on your computer's clock. If you create a world at 7:00 PM in real life, you'll spawn into a world that's already experiencing evening/night time.

Non-Intrusive: Doesn't interfere with other time-related mods or vanilla mechanics
Memory Efficient: Minimal memory footprint with smart caching
