Sealed Time Capsule

Time Capsule

Leave something for your future self, or for everyone on your server.

How it works

1. Craft a Time Capsule and place it.
2. Choose how it keeps time: real-world days or in-game days.
3. Pick how long it stays sealed, from 1 to 365 days.
4. Put in your items and written books, then seal it.
5. Until time runs out, the capsule stays shut and can’t be broken open. Right-click it to see how long is left.
6. When the time is up, open it and find what you left behind.

Great for

• SMP servers: bury capsules at the start of a season and open them together at the end.
• Long survival worlds: write a note to yourself and read it 100 days later.
• Creators: “opening our one-year time capsule” episodes.

Lightweight by design

• Capsules never tick. Time is only checked when someone interacts with one.
• Plain block model, no custom renderers or shaders.
• No extra libraries (Fabric only needs Fabric API).

Real-world or in-game days?

• Real-world days use the real clock, so they keep counting while the game or server is off.
• In-game days count Minecraft days, so they only pass while the world is running.

Configuration

Edit config/timecapsule.properties to set the default time mode, the default and maximum number of days, and whether the whole server is told when a capsule opens.

Supported versions

Install it on both the client and the server.
