Is it possible to get the time spent per issue comment?

I want to get the time spent per commenter for a single issue.
How can i get the time spent per author by subtracting the current author’s time from the previous author’s time and display it in a bar graph by issue?

Hi @dkei ,
It won’t be possible to see comment author and different times of their comments on one issue and then to calculate time difference between different authors.

Best,
Gerda
