Stopwatch

This plugin displays a time on to each player's hotbar and the time can be stopped or paused.

UPDATE: Placeholder support! %stopwatch_time% for time message and %stopwatch_seconds% for raw seconds passed.

NOTE: this plugin should work for every version of minecraft even new ones without updating it as the spigot hotbar api has been stable since 1.9
