[O] Inactive time stamps along with CLOCK: entries?

[Tommy Kelly]

Question for Bernt, but maybe more widely useful.

Bernt, in some of your org-capture-templates, you often include a %U
timestamp as well as clocking in the item in question. for example:

("j" "Journal" entry (file+datetree "~/git/org/diary.org")
               "* %?\n%U\n  %i" :clock-in t :clock-resume t)

Why do you do that extra \n%U? Since the timestamp is going to be
identical to the first entry in the CLOCK: line, and since you can
have/not-have clocking items show up in the agenda, why have both the
:CLOCK line and the timestamp? What else do you get from having a
timestamp that you don't get from the CLOCK: line alone?

thanks,
Tommy
