Time Formatter
by m3z0id
Players who read timestamps in chat see Discord-style times converted to their own clock once Time Formatter is installed on the client.
What it does
Time Formatter detects timestamps in incoming chat messages and rewrites them into the local time zone of the computer running the game. A message sent with a UTC timestamp is shown in the viewer's own zone, so a GMT+1 player sees a server event listed for Monday January 1 2024 at 01:00 without doing any arithmetic. The conversion covers Unix timestamps in seconds and the special words yesterday and tomorrow, which resolve to the matching day.
The mod can display a time relatively, for example 5 minutes ago or 2 hours, and an optional single character chooses the output format. Its formatting works only with the mod installed, while players who lack it still see the raw text sent by the author. The project is open source under the MIT License and its source code and issue tracker are public. Fabric API is required, and the mod is published for Fabric only.
Key features
Automatic formatting
Timestamps in chat are detected and rewritten without any command or manual step.
Local time conversion
Each timestamp is converted to the time zone set on the viewer's computer before it is displayed.
Relative time
A timestamp can be shown as a distance from now, such as 5 minutes ago or 2 hours ago.
Unix seconds and keywords
Unix timestamps in seconds are read, and the words yesterday and tomorrow map to their matching dates.
Optional output format
A single character selects the output style, and no default short or long date style is imposed.

Use cases
Who it’s for: Players who join multiplayer servers or chat groups that post timestamps from other time zones, and who want those times shown in their own clock. Server owners need nothing extra, because the formatting happens on the client.
How it compares
TimestampBro is a Fabric client mod for 1.21.11 – 26.3 under All rights reserved, so it is not open source. Timestamp Chat is open source under the MIT License and covers Fabric, Forge and Quilt for 1.15.2 – 1.21.4, a wider loader and version set than Time Formatter. Chat Tweaks is also open source under the MIT License, but it targets Fabric for 1.21.2 – 1.21.4 and covers chat more broadly than timestamps.
