It's a dead simple little doodad, mkay. You start a task, it takes a timestamp and puts a label, you end a task it stamps the time. You literally don't need much else. It's a little like interstitial journaling, but for me it's useful for making invoicing simpler.

I've packaged a python executable and an html version that work as standalones. The base python script is also included for them that feels like fiddling with it. I don't need to.

If you want to build your own from the .py, use pyinstaller --onefile. EZ PZ.
