How to generate CLOCKSUM property from time ranges?

How to generate CLOCKSUM property from time ranges?

Greetings all,
I am looking into using `org-invoice` to generate some invoices. It uses
the CLOCKSUM property, which according to the docs gets auto-generated when
the clock entries are summed in a subtree.

Concretely, docs say: "CLOCKSUM: The sum of CLOCK intervals in the
subtree.  ‘org-clock-sum’ must be run first to compute the values in the
current buffer."  However, `org-clock-sum` is a non-interactive function,
and evaluating it by hand doesn't do anything for me.

Org-clock-report is able to generate the table with total subtree sums, but
doesn't set the CLOCKSUM property.

Question: how do I get CLOCKSUM property generated and stored in a subtree
with timestamps so that org-invoice functions can pick it up?

I haven’t used the CLOCKSUM property (or org-invoice), but my
understanding is that it’s a special property that should not actually
be set in the property drawer: ‘(info "(org)Special properties")’.

Running org-clock-sum doesn’t generate a property drawer, but it does
store the value as a text property.  Say we have this file:

--8<---------------cut here---------------start------------->8---
* TODO things
:LOGBOOK:
CLOCK: [2019-01-12 Sat 17:33]--[2019-01-12 Sat 17:40] =>  0:07
:END:
--8<---------------cut here---------------end--------------->8---

org-invoice retrieves the CLOCKSUM value with org-entry-get.  Here’s
what we get if we run that in the above buffer, before and after calling
org-clock-sum:

  (org-entry-get nil "CLOCKSUM" nil)   ; => nil
  (org-clock-sum)                      ; => 7
  (org-entry-get nil "CLOCKSUM" nil)   ; => "0:07"

So, running org-clock-sum (or any function that calls org-clock-sum),
does generate and store a value that org-invoice can use; you just can’t
see it easily.
