As sensible as anything :) 

I recently added my version, using decode-time and nth, as a helper
function to my .emacs. I feel sure that it must already exist
*somewhere* in Emacs but I searched quite a while for it and didn't find
it. I will use this again below:

#+begin_src emacs-lisp 
  (defun time-as-calendar-date (time)
    "Convert time in Emacs' time format to a calendar date list (MONTH DAY YEAR)"
    (let ((parsed-time (decode-time time)))
       (nth 4 parsed-time)
       (nth 3 parsed-time)
       (nth 5 parsed-time))))

Here you might find it useful to grab the value of the :default-time key
from org-capture-plist (which should contain either the time you entered
at the date prompt during capture, or the current time, in Emacs' time
format). Then, using the functions above, you can say something like
this in your hook:

#+being_src emacs-lisp
(let* ((default-time (plist-get org-capture-plist :default-time))
       (date (time-as-calendar-date default-time)))
  (org-update-clocktable-on-date date))

> 2. Changing the org-clock-report options in your function above, but not the defaults.
> For the second point, is there some trick to swap a global variable for the run of a function? The variable in this case would be org-clocktable-defaults.

Emacs Lisp has dynamic scope by default, which makes this is pretty easy
in general: just set the value you want to use in a let form around the
code that uses this variable, like:

(let ((org-clocktable-defaults your-custom-value-here))

No problem! That's what this list is for. I recently spent a fair amount
of time digging through the datetree stuff myself, so I was glad to have
a chance to share what I learned.
