@hi This might not be exactly the same as what you are doing. But I've been using a go script I wrote for the past 5 years to keep track of how long I do things on my computer.

I have it integrated as a hook with my editor (kakoune) as well as tmux, and various other programs.

Just recorded a short vid to show it off.

in my current situation it just doesn't make sense. i'm switching from task to task too often. i guess that's normal when a three-year old is running around :)
