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.

If you use M-S-Up and M-S-Down on the CLOCK line of a task then, in addition to adjusting that clock time, it will also adjust the clock entry of the previously clocked-in task.

Practically what this means is that, in your scenario, if you clock into your new task 40 minutes late, just adjust its start clocking time back 40 minutes with M-S-Down and it will also adjust the end time of the previous task so there's no overlap.

I use this all the time for exactly the scenario you describe.

    Oh, that is even finer! Indeed, I used legoscia' suggestion, then adjusted the preceding clock accordingly. I will try your more thorough sugguestion. Thanks! Commented Oct 3, 2015 at 15:58

    Wouldn't that be M-S-Down to move the clock backwards in time 40 minutes?

    Eek, yes you're right. How could that stay wrong for nearly six years?! Corrected, and thanks for the pointer. Commented Jul 16, 2021 at 17:03

One way to manipulate the time is to clock out, go to the clock entry, and change it with Shift-up and Shift-down. If point is on the minutes, it will change by 5 minutes for each key press, and if point is on the hours, it will change by one hour for each key press.

    While this does adjust the clock, it will cause an overlap with the previously clocked-in task, which is what the questioner was trying to avoid. I think my answer avoids that issue (additionally use the META key when bumping clocks up and down). Commented Oct 3, 2015 at 10:51
