I’ve had this in my blog queue for sometime but before I could get to it, Sacha ran with it in her Emacs News post. I was going to forego mentioning it but after my Clocktables post, I decided that would be a useful adjunct to that post. After all, if you’re going to be using clocktables, you really should be sure that your clocking data is accurate and this post from Marcin Borkowski shows a nice way of helping to do this.
It turns out that the Org mode agenda has a builtin way of checking for anomalies in clock data. That means things like overly long clock intervals. Borkowski’s post talks about some of these cases and shows how to invoke the checks.
As Borkowski writes, you can check out the details by looking at the docstring of org-agenda-clock-consistency-checks but that function is defined with a defcustom so you’ll need to search for it in org-agenda.el directly.
