WhenChat
Prepends a [HH:mm:ss] timestamp to every received chat message — never lose track of when something was sent.
WhenChat
WhenChat is a lightweight, client-side mod that automatically prepends a [HH:mm:ss] timestamp in front of every chat message you receive in Minecraft. Available for Fabric, NeoForge, and Forge.
Ever wondered exactly when that message in chat was sent? Whether you're on a busy multiplayer server, taking screenshots for proof, or just want a quiet reference for the time of day without opening the F3 debug menu — WhenChat has you covered.
Features
- Automatic timestamps — every incoming chat message is tagged with the current time in
[HH:mm:ss]format - Zero configuration — install, launch, done
- Client-side only — works on any server, vanilla or modded, no server-side install needed
- Multi-loader — Fabric, NeoForge, and Forge JARs available for every supported MC version
- Lightweight — a single mixin, no performance impact
- Subtle styling — timestamps are rendered in gray so they don't distract from the actual message
Example
Before:
<Steve> hey, are you online? <Alex> sup
After:
[18:42:07] <Steve> hey, are you online? [18:43:21] <Alex> sup
