I still fumble for the right way to use a timestamp.

Right now, I want to automatically add a timestamp (time of capture) to an entry when I use org-capture. What's the right way to do this?

Should I add an inactive timestamp right down below the heading? I was thinking of doing something like CAPTURED ON: [2021-10-02]. This is easy to do inside org-capture-templates. But then the first words can have special meanings (as in DEADLINE: ) which makes it look awkward.

Or should I just add it as a custom property? If so, are timestamps completely legal inside the PROPERTIES drawer (and will they always be?). I've seen other people add a simple date without the brackets, but this won't cut it for me cause I want to use the timestamp with org-sparse-tree.

Or should I add it as a list entry to the LOGBOOK drawer? Accomplishing this with org-capture needs some extra hacking, but this seems like the most semantically correct option.

Is it just me, or is org-mode syntax quirky? I'm confused about something that seems like a very common use-case?
