[O] taskjuggler subtract scheduled and deadline

[e***@openmail.cc]

Hello,

I am trying this:

#+BEGIN_SRC org
,* TODO Pay the rent
:taskjuggler_project:
SCHEDULED: <2017-12-29 Fri 09:00> DEADLINE: <2017-12-29 Fri 11:00>
#+END_SRC

which gives me this:
#+BEGIN_EXAMPLE
repeat.tjp:13: Error: The end date (2017-12-29-00:00-+0000) must be
after the start date (2017-12-29-00:00-+0000).
#+END_EXAMPLE

I tried modifying ox-taskjuggler.el:
#+BEGIN_SRC diff

(and scheduled (org-timestamp-format scheduled "%Y-%02m-%02d"))
+ (and scheduled (org-timestamp-format scheduled "%Y-%02m-%02d
%R"))
+ (and scheduled (org-timestamp-format scheduled "%Y-%02m-%02d %a

+ (and scheduled (org-timestamp-format scheduled "%Y-%02m-%02d %a
%T"))
(and (memq 'start org-taskjuggler-valid-task-attributes)
(org-element-property :START item)))))

#+END_SRC

but I got the same error. Is there a way to set starting and ending
times with a resolution of hours or minutes to be exported with
taskjuggler? Thanks!

Hi Edgar,

sorry your question didn't receive answer - I'm copying
ox-taskjuggler.el maintainers in case that helps.

@Christian: I don't remember if you are still using and
maintaining ox-taskjuggler.el -- feel free to correct me
if I'm wrong!

Thanks,

No I'm barely using it anymore, let alone maintaining it.

As for Edgars question

AFAIK there isn't. Your patch was good start, but your expressions
inside the (or ...) were such that the one that collected the time was
never executed.

I see three options:

1. Hack the exported taskjuggler file. A hack but gets the job done
2. Try to use the START attribute on the node
3. Improve the source of ox-taskjuggler.el as you've started.

Hope that helps
Christian
