Windows 10 (64 bit), Emacs 25.1
Suppose I have one org mode file. In this file I have my tasks with it's duration. After all my tasks was finish I calculate all tasks duration. I use command:
As you can see the all tasks duration = 22.16 hours. OK!
As you can see the duration of task Task-1144 = 3.50 + 0.08 + 3.50 = 7.08 hours.
So the question is: How in Emacs I can calculate duration of specific task? Thanks.
