I also work with a tool that tracks the time I spend working on a project.
It´s free, but there´s also a luxurious version available.
It is a VST plugin that automatically starts and stops when the project is opened and closed in CB.
This way, you can see at the end how much time you actually spent working on the project.
Of course, it can also be paused when taking a break.
The tool is free and developed by HOFA.
