I'm trying to give each header entry a timestamp. To do this I create a
drawer like this:

:PROPERTIES:
:CUSTOM_ID: [2013-03-19 Tue 14:26]
:END:

Initially, I do C-u M-x org-insert-drawer. This gives me

:PROPERTIES:

:END:

Then I do C-c C-x p and choose CUSTOM-ID. Then I insert a timestamp. Here's
what it looks like (expanded):

:CUSTOM_ID: [2013-03-19 Tue 19:34]
:END:

:PROPERTIES:
:CUSTOM_ID: [2013-03-19 Tue 19:42]
:END:

I'd like to know the best practice for adding such timestamps. Am I gaining
anything by enclosing the timestamp in such an elaborate drawer? Are these
two commands the best way to do this? Or is there a more automated approach?

In general, I can't help but marvel at the ad-hoc, on-the-fly data
management possibilities org-mode offers. It seems like the sky's the
limit. But I'd like opinions on whether I'm stumbling along a blind alley.
