Thanks! I think that's going to be what I'm looking for, but I got an error:

let: Wrong type argument: integer-or-marker-p, nil

I traced it down to the =org-element-property :contents-begin= call which essentially ends up looking like this:

(org-element-property :contents-begin '((clock (:status closed :value (timestamp (:type inactive-range :raw-value "[2018-08-05 Sun 02:35]--[2018-08-05 Sun 03:06]" :year-start 2018 :month-start 8 :day-start 5 :hour-start 2 :minute-start 35 :year-end 2018 :month-end 8 :day-end 5 :hour-end 3 :minute-end 6 :begin 28124 :end 28171 :post-blank 1)) :duration "0:31" :begin 28112 :end 28180 :post-blank 0 :post-affiliated 28112 :parent (drawer (:begin 28097 :end 28191 :drawer-name "LOGBOOK" :contents-begin 28112 :contents-end 28180 :post-blank 0 :post-affiliated 28097 :parent nil))))))

Then contents-begin isn't being accessed for some reason. I don't know elisp well enough to know why just by looking at that. The raw output I got from my point being over a TODO I yanked from the messages buffer was:


(clock (:status closed :value (timestamp (:type inactive-range :raw-value "[2018-08-05 Sun 02:35]--[2018-08-05 Sun 03:06]" :year-start 2018 :month-start 8 :day-start 5 :hour-start 2 :minute-start 35 :year-end 2018 :month-end 8 :day-end 5 :hour-end 3 :minute-end 6 :begin 28124 :end 28171 :post-blank 1)) :duration "0:31" :begin 28112 :end 28180 :post-blank 0 :post-affiliated 28112 :parent (drawer (:begin 28097 :end 28191 :drawer-name "LOGBOOK" :contents-begin 28112 :contents-end 28180 :post-blank 0 :post-affiliated 28097 :parent nil))))


To be able to work with it in org mode I just put a ='= in front of it like:

        #+BEGIN_SRC elisp
        (org-element-property :contents-begin '((clock (:status closed :value (timestamp (:type inactive-range :raw-value "[2018-08-05 Sun 02:35]--[2018-08-05 Sun 03:06]" :year-start 2018 :month-start 8 :day-start 5 :hour-start 2 :minute-start 35 :year-end 2018 :month-end 8 :day-end 5 :hour-end 3 :minute-end 6 :begin 28124 :end 28171 :post-blank 1)) :duration "0:31" :begin 28112 :end 28180 :post-blank 0 :post-affiliated 28112 :parent (drawer (:begin 28097 :end 28191 :drawer-name "LOGBOOK" :contents-begin 28112 :contents-end 28180 :post-blank 0 :post-affiliated 28097 :parent nil))))))
        #+END_SRC

If that's the correct way to do that translation, then maybe we are using different org mode versions? I'm using 9.1.9.

I think something like this is what you are looking for:
