Simple Stopwatch

This client-side mod adds a stopwatch function to the Minecraft clock.

By holding the clock in the main hand, players can use the mouse buttons to control the stopwatch. The measured time is displayed instead of the crosshair, and entities and blocks cannot be interacted with during stopwatch use.

Pressing the right mouse button starts or pauses the stopwatch.

Pressing the left mouse button displays the elapsed time when the stopwatch is running. When the stopwatch is stopped, pressing the left mouse button resets it.

The stopwatch also starts or displays the elapsed time when passing through a sign with the word “racetrack” in the top line.

This feature makes timing measurements on a racetrack automatic and accurate.
