Chrono API
by Rolmi
Chrono API is a Forge library for Minecraft 1.20.1 that controls the flow of in-game time for named time fields, entities, blocks and chunks.
What it does
Time control in Chrono API works through named time fields. A field can target entities, blocks, geometric areas, loaded chunks or whole dimensions, and can be slowed, accelerated, paused or resumed. Speeds range from a simulation rate of 0.0001 up to 100 ticks per second, with normal speed at 20 ticks per second. Fields can also follow an owner so that time control moves with a player.
Entities can be exempted from pauses and tick-rate changes through UUID whitelists, and an immunity list accepts living-entity holders. Rewind replays recorded history for entities, blocks, items, projectiles, inventories and supported players. Rewind restores recorded state rather than reversing operations. Coverage depends on which history is loaded and which integration paths other mods use. Chrono API is a prerequisite for Pugmeowla's Infinity Stone Core and separates the reusable time-control engine from Deus Chrono-Machina. Deus Chrono-Machina v7.x is listed as a required dependency, while the separated engine remains compatible with v6.x.
Key features
Named time fields
Time fields target entities, blocks, geometric areas, chunks and dimensions, and each one can be slowed, paused or resumed separately.
Simulation speed control
Rates run from 0.0001 to 100 ticks per second, with normal speed at 20 ticks per second, and a multiplier field selects the calculation.
Rewind history
Recorded history covers entities, blocks, items, projectiles, inventories and supported players, and restores their recorded state.
Whitelists and immunity
UUID whitelists exempt entities from pauses and tick-rate changes, and an immunity list accepts living-entity holders.
Command and Java access
Chrono commands cover gameplay integrations, testing and server administration, and a Java API lets other mods control time without commands.

What the author says
Chrono API is a Minecraft Forge mod for controlling the flow of time. Originally extracted from Deus Chrono-Machina, it separates the reusable time-control engine from the original mod’s gameplay content. Other mods and Palladium power packs can use its time-manipulation features without requiring Deus Chrono-Machina…
