thank you carbon2! also, this thing improve calculation of donation value to blender developers team
for example 1h = 60uBTC
This is nice addon. Thanks!
Link is dead. Has the project moved to another host?
no, i moved 2.7x addons. all is still here https://github.com/uhlik/bpy
Thanks, I recent upgraded my OS and forgot to backup my Blender scripts. :S
Will there be an update to 2.8?
i will try… hope api did not change too much
updated for 2.80
get it here: https://github.com/uhlik/bpy
i stopped using it for my projects, so i didn’t test it much. but it looks like it is working well, the same as before. if you are using it, please tell me if it is ok… or not…
Thanks for the update! Really useful addon 
well, by error it looks like you have installed addon directly into blender program files and it has no write access there, put addon py file to user data. docs https://docs.blender.org/manual/en/2.80/advanced/blender_directory_layout.html says it should be %USERPROFILE%\AppData\Roaming\Blender Foundation\Blender\2.80\ so put it to %USERPROFILE%\AppData\Roaming\Blender Foundation\Blender\2.80\scripts\addons\ and it should work. i am not windows user, so i can’t check.
Thank you!
It worked 
And also thank you for writing down the “path to the folder” because I would have a hard time understanding the manual even with you linking me exactly to the answer 
So in order for me to find out how much time I’ve spent on a project I have to open the csv file and do a bunch of math between all the different time stamps? Is there a place where it simply displays how much time has elapsed?
Also I keep all my blends in one directory. Why doesn’t this just track time for each blend file instead of using directories as projects?
Alternatively, you can also use this addon: TimeMe
data can be read in addon preferences, read docs https://github.com/uhlik/bpy#time-tracker-for-blender-280
