Current time timestamp in org-capture-templates

Question

In org-mode org-capture templates, what is the way to insert current time timestamp?

I've tried %U like so:

(setq
 org-capture-templates
 (quote
  (
     ("k" "Capture an item and schedule it for tomorrow" entry
      (file+headline "today.org" "_tomorrow")
      "* TODO %^{Task Title} %^G
SCHEDULED: %t
Added: %U @ %a" :immediate-finish t))))

but the %U shortcode always produces 00:00 time and the date is the same as the agenda view date at which the point is located at the time the org-capture is invoked.

By the way, I'd also like some suggestions on how to produce a "tomorrow" timestamp in the template, but that is probably a topic for another question.

Answer 1

According the help for org-agenda-capture (bound to k in agenda views)

Call ‘org-capture’ with the date at point. With a ‘C-1’ prefix, use the HH:MM value at point (if any) or the current HH:MM time.

It works correctly if you position the cursor on a line that has a time. Otherwise the time seems to always get set to "00:00". The function responsible for getting the time is org-get-cursor-date. This function claims:

Return the date at cursor in as a time. This works in the calendar and in the agenda, anywhere else it just returns the current time. If WITH-TIME is non-nil, returns the time of the event at point (in the agenda) or the current time of the day.

Everywhere except in on a line in an agenda view that doesn't have time, the function behaves as advertised. But if it doesn't find some kind of a timestamp, it defaults the current day at midnight. The relevent piece of code is

(setq date (calendar-gregorian-from-absolute day)
        defd (encode-time 0 (or mod 0) (or hod 0)
                  (nth 1 date) (nth 0 date) (nth 2 date)))

mod and hod are the minute and hour, but aren't getting set and thus default to 0.

This seems to contradict the stated intent of the function and is likely a bug rather than a feature.
