I was once one of the many people who apparently originally
misunderstood what "SCHEDULED" meant, and used to set it to like, an
appointment time.

It seems the appropriate thing for what I actually meant was to just
put a timestamp anywhere in the entry and that works out well.  A lot of
people put it on the header apparently, and that seems insane to me.

I kind of miss how nice it was back when I misunderstood how events work
(escept for all of those non-TODOs staying around forever on my
agenda..) where I had a dedicated property for this, and pressing
C-c C-s would always change that property.

What I'm saying I guess is:
 - Is there a popular property name for when something should be
   happening, in a non-TODO way?  I've thought of "OCCURANCE" but maybe
   that isn't the best (I suspect not)
 - Maybe if we formalize this property, we should make a command for it?
   Maybe C-c C-S-o?
 - It would be nice to formalize this so we could actually steer people
   in the right direction in the docs.

That's what I do.

Maybe I lack background, but why do you think it's not appropriate for
this use?

So when it comes to TODO like things, SCHEDULED is when you should start
working on it, DEADLINE is when it's due.

One side effect of doing it "wrong" is that non-TODO items that are
SCHEDULED stay on your agenda forever (or until archived, and still
forever with archive view on), which is nasty.

There is a special property name for active timestamps: TIMESTAMP. You
can access the first active timestamp in an entry (either with column
view or org-entry-get) via the special property TIMESTAMP. Inactive
timestamps = TIMESTAMP_IA.

There is currently a command to change plain active timestamps from the
agenda. (In fact, this will also change SCHEDULED and DEADLINE
timestamps when on a SCHEDULED or DEADLINE line.)

        org-agenda-date-prompt (>)

AFAIK, there is no similar built-in function to call on headlines in org
files. One can, however, navigate to the timestamp and use the
Shift-arrow keys or C-c . to change the appointment.

What would you suggest adding to the following pages?

(info "(org) Creating timestamps")
(info "(org) Special properties")

Best,
Matt

There is a nice FAQ on this:

Well, you can use it that way.
The point is: Scheduled items behave differently to timestamped items.
If you prefer the behaviour scheduling provides you with, go for it.

I just did a quick check. 
It seems to me that timestamps within a property work.
So, if you prefer, you can set your timestamps in a property like this:

*  NEXT Task 2
   :LOGBOOK:
   :END:
   :PROPERTIES:
   :DATE:     <2011-04-12>
   :END:

If you want a convenient keybinding to set this property, this seems
to work:

--8<---------------cut here---------------start------------->8---
(defun my-org-set-date ()
  "Set DATE Property via org-read-date."
  (interactive)
  (org-set-property "DATE" (concat "<"(org-read-date)">")))

(define-key org-mode-map (kbd "C-c C-S-s") 'my-org-set-date)
--8<---------------cut here---------------end--------------->8---

Okay, there is still setting it in the agenda.
There are already functions doing special treatment for e.g. effort.
It should work to grab it and modify it to our needs ...

--8<---------------cut here---------------start------------->8---
(defun my-org-agenda-set-date ()
  "Set the DATE property for the current headline."
  (interactive)
  (org-agenda-check-no-diary)
  (org-agenda-show)   ;;; FIXME This is a stupid hack and should not be needed
  (let* ((hdmarker (or (org-get-at-bol 'org-hd-marker)
		       (org-agenda-error)))
	 (buffer (marker-buffer hdmarker))
	 (pos (marker-position hdmarker))
	 (inhibit-read-only t)
	 newhead)
    (org-with-remote-undo buffer
      (with-current-buffer buffer
	(widen)
	(goto-char pos)
	(save-excursion
	  (org-show-context 'agenda))
	(save-excursion
	  (and (outline-next-heading)
	       (org-flag-heading nil)))   ; show the next heading
	(goto-char pos)
	(call-interactively 'my-org-set-date)
	(end-of-line 1)))))

(define-key org-agenda-keymap (kbd "C-c C-S-s") 'my-org-agenda-set-date)
--8<---------------cut here---------------end--------------->8---

Did some quick testing, it *seems* to work.
But I have no expertise in elisp (or programming for that matter), so
this is probably "wrong" in one way or the other :).

Oh, this was not a "How can I do x?" mail, but a request to formalize
this in org core .... 

Nevermind ;)

Yup, its what i use to make sure my journal entries appear in my agenda,
the snipped from org-capture-templates is

 ("j" "Journal" entry
  (file+datetree "journal.org")
  "* %?\n	:PROPERTIES:\n	:DateCreated: %T\n	:END:\n%i\n%a")


very handy.

Hm, that's interesting.  But I'm not talking about a way to access it
via elisp, I'm talking about a place to actually put it in say, the
property drawer.  Say:

** Pick up bike from the shop
   :PROPERTIES:
   :OCCURANCE: <2011-04-12 Tue 19:00>
   :END:

etc.

It's nice to know there's a meta-property for TIMESTAMP, but I'm
specifically looking for a nice place to put that timestamp away.  This
is for cleanliness / easy get-set purposes.

That's useful, and would change this property even if I put it in such a
drawer... provided that property already existed.  But what if I want to
insert something on a currently un-OCCURANCE'd (or whatever) thing?  I
don't want it to go on the headline, that looks gross.

That's entirely dependent on if we can suggest a property for this
behavior.  It doesn't have to be mandatory.

I'm partly trying to see if other people want this as much as I do.
Surely I'm not the only one who finds putting active timestamps on the
headline or scattered just anywhere in the entry kind of gross?

I do appreciate your useful reply, though!

O.K. I wasn't clear what you meant by property in the original post.
What about :APPOINTMENT:?

Here's a simple proof of concept:

(defun my-org-add-occurrence ()
  (interactive)
  (org-set-property "OCCURRENCE" 
		    (concat "<" (org-read-date t) ">")))

It turns...

--8<---------------cut here---------------start------------->8---
* A headline
--8<---------------cut here---------------end--------------->8---

...into...

--8<---------------cut here---------------start------------->8---
* A headline
  :PROPERTIES:
  :OCCURRENCE: <2011-04-12 20:00>
  :END:
--8<---------------cut here---------------end--------------->8---

> I'm partly trying to see if other people want this as much as I do.

I keep them right beneath the headline, which I find to be just the
right mix of tidiness and visibility.

--8<---------------cut here---------------start------------->8---
* A headline
  <2011-04-12 20:00>
--8<---------------cut here---------------end--------------->8---

Best,
Matt

The name could be critical. To avoid any confusions/collisions I would
recommend to use just that name TIMESTAMP for easy get/set access:

* _appointment_ that _occurs_ at bike shop
  :PROPERTIES:
  :TIMESTAMP: <2011-04-12 Tue 19:00>
  :END:

> I'm partly trying to see if other people want this as much as I do.

I would like to have generally some special properties case by case
inside _or_ outside of the properties drawer, like e. g. CLOSED,
CATEGORY, TAG etc. See also the current discussion
http://thread.gmane.org/gmane.emacs.orgmode/40801/focus=40813
and the similar discussion linked there.

In this case of TIMESTAMP it would be allowed e. g.

* _appointment_ that _occurs_ at bike shop (keyword inside drawer)
  :PROPERTIES:
  :TIMESTAMP: <2011-04-12 Tue 19:00>
  :END:
* _appointment_ that _occurs_ at bike shop (keyword outside drawer)
  :TIMESTAMP: <2011-04-12 Tue 19:00>
* _appointment_ that _occurs_ at bike shop (keyword-less, at least for
backward compatibility)
  <2011-04-12 Tue 19:00>

"Appointment" makes a lot of sense.  +1.  Better than "occurance" I
think. :)

Maybe you're already aware, but since TIMESTAMP is a "special property"
it currently isn't legal to use it as a property.  But maybe you're
suggesting changing that?

Yes, I suggest to remove this limitation and would prefer TIMESTAMP
much over OCCURANCE, APPOINTMENT (not every occurrance is an
appointment) or any other name to avoid a second name for the same
behavior of the existing special property TIMESTAMP and to avoid
confusions/collisions at other places like e. g. selecting a property
for a column view. In the sense of special properties I also suggest
to allow different formats:

* _appointment_ that _occurs_ at bike shop (keyword inside drawer)
 :PROPERTIES:
 :TIMESTAMP: <2011-04-12 Tue 19:00>
 :END:
* _appointment_ that _occurs_ at bike shop (keyword outside drawer)
 :TIMESTAMP: <2011-04-12 Tue 19:00>
* _appointment_ that _occurs_ at bike shop (keyword-less, at least for
backward compatibility)
  <2011-04-12 Tue 19:00>

With this I imagine that reading and writing the special property
TIMESTAMP would address the first found with the chosen format or, if
not found, for writing create one with the chosen format. The chosen
format would of course default to the now only format "keyword-less",
or with e. g.

#+SPECIAL_PROPERTIES: TIMESTAMP=drawer:PROPERTIES   <= example syntax
only to get an idea

could be changed to the first format "keyword inside drawer". The
format "keyword-less" seems to overlap with the others which might
need some more care.

Interesting, I like that style.  My main concern is that newer orgmode
files written in this form might break in older versions of orgmode.

That looks like it should work.

I did some quick checking - I believe it would be possible to
make DEADLINE, SCHEDULED and CLOSED properties instead of having
them in the second line.  You and Matt have just shown that
an arbitrary property (like appointment) can serve as the
standard date of an entry.  The parser that is looking for CLOSED,
SCHEDULED, DEADLINE is lenient and does not mind if there is an
additional colon in front of the keyword.  So if you have a
(currently not allowed) :SCHEDULED: property, it will
behave correctly when constructing the agenda.

If I am not mistaken, we could introduce (not-trivial, but
likely without major headaches) an option like
org-planning-use-properties or so.  Much will work out of
the box.  The places where changes are needed are these functions:

org-add-planning-info
org-entry-put
org-entry-get
org-entry-properties

The main problem would be that it would not be trivial to have
mixed entries - user would have to make a decision if they want
planning info in the property drawer or not.  Things would not work well
or require a lot of extra checking with files that as mixed (agenda
production would work OK, but changing dates may cause problems.
But I guess this could be handled one way or another.

As I have explained earlier, to have planning info like tags and the
TODO keyword outside of drawers has historic reasons, but it is
also good for newcomers.

Are your concerns concrete?

I have thought about and tested this already before: The three example
items above show up in the agenda, and are still correct even after
changing with `S->'. So this "newer/future" Org file format works even
with the "older/today" Org software. This is because the Org software
of today flexibly binds the special property TIMESTAMP per item to the
first active timestamp (i. e. "<>", not "[]") that is not prefixed
with `SCHEDULED: ' or `DEADLINE: '. This binding is the reason why I
would stick to the name TIMESTAMP when it comes to possibly new
features that should write this special property keyword explicitly
for this kind of timestamp. The sibling (not `C-c .') of `C-c
C-s'/`C-c C-d' that you suggested originally would be such a feature.

That's interesting, and no, my concerns weren't concrete.  I just tried
inserting the timestamp property via C-c C-x p and saw that it error'ed,
and wondered if there were further blocks around orgmode's system than
just the property insertion tools.
