Get a timeline of clocked time in org-mode

Question

In an attempt to figure out how I've been spending my time, I've started logging my time spent on different tasks with org-clock-in and org-clock-out.

I often find myself editing clock entries by hand, for instance, when I realize that I should have clocked in 20 minutes ago. So is there a way to see a) which clocks are currently running (or haven't been terminated properly because I forgot to clock out before exiting Emacs), and b) a list of clock entries?

I can get a table that shows the total amount of time I've spent on each task, but I can't get a list that says,

9:00--9:30   Project A
9:18--10:00  Project B
10:00--11:00 Meeting
11:45--13:00 Lunch

which would let me see overlapping times (like Projects A and B, above) and gaps (like the one between Meeting and Lunch). Is there such a thing?

Answer 1

org-agenda-log-mode or C-u C-u l in your Agenda will give you exactly this table. Depending on the org-agenda-log-mode-items variable it will restrict the agenda to entries that have been clocked or closed today (that's the default setting). To add visual emphasis to gaps and overlaps of your clocking chunks look into the org-agenda-clock-consistency-checks variable.
