I often forget either to clock out of a task, or to clock a different activity in.
For instance, I was working on a (clocked) task right now, then my manager walked in and we embarked on a discussion which lasted a good 40 minutes... So not negligible.
What is the best way to go about this? I would like - if possible - to subtract the time of this discussion from the main task I was working on, and add it to a new activity.
