What's new

MCRealTime 4.8 — Major Rewrite

Version 4.8 is a major rewrite of MCRealTime.

Added

  • CLOCK and location-based SOLAR synchronization modes.
  • Offline location lookup with bundled GeoNames data and tab completion.
  • New /mcrt status, mode, location, reload, and update commands.
  • Asynchronous GitHub Releases update checks and optional staged downloads.
  • Safe, versioned configuration migration with complete legacy backups.

Changed

  • Reorganized runtime, time calculation, configuration, location, and updater components.
  • Improved world-state handling and reduced unnecessary time-setting calls.
  • Standardized the recommended installed filename to MCRealTime.jar.

Removed

  • Replaced the old updater and legacy time-handling implementation.
  • Removed dependence on global server reloads for MCRealTime configuration changes.

Fixed

  • Corrected legacy time-calculation issues and improved console command handling.
  • Improved compatibility with modern Paper world clocks, renamed game rules, and dimensions without mutable clocks.
  • Restores previously configured world game rules when MCRealTime stops or reloads.

Tested combinations

  • Spigot 1.8.8 / Java 8
  • Paper 1.14.4 / OpenJDK 8
  • Paper 26.3 build 140 / Temurin 25.0.4
