My solution is by no means shorter than the one by Tobias, and I probably would not have written it, had I not been interested in one of the side products: A function which collects me all clock ranges with full heading information in a certain time interval, which is the basis for further processing. Based on this function and some other helpers, I implement a dynamic block which you can use like a normal org clocktable block.
So, you just write the following, and upon hitting C-c C-c on the BEGIN line, it will expand to the table:
#+BEGIN: nagora-report :buffer "nagora-example.org" :day 2016-02-05
#+END:
#+BEGIN: nagora-report :buffer "nagora-example.org" :day 2016-02-25
#+END:
These two blocks will expand to the following:
#+BEGIN: nagora-report :buffer "nagora-example.org" :day 2016-02-05
#+CAPTION: timesheet for day 2016-02-05

The counters in brackets can be easily cleaned up if desired. Currently the dynamic block wants an open buffer (:buffer argument) but it is trivial to change that to a file path.
I still wonder at this special timesheet reporting format, because it also is not translation invariant, so the same amount of work will look different, if you begin at the start of an hour or some time later. But sometimes it is shorter to implement such a function than discuss with management ;-)
I hope this is useful. It certainly can be cleaned up a bit and made more consistent.

Note: The solution is inspired by the org-clock-sum code and analogous to that function I chose not to invoke the full org parsers, but to use a probably more efficient direct parsing, since I'm only interested in headlines and clock lines.
The regexp search function uses an interesting concept copied from org-clock-sum involving an "or"-ed regexp which either matches a headline or a clock time range. That idea is kind of nice, since it allows one to implement a simple state machine with a single regexp in this way.
org-clock-sum. One can give a headline filter, a start time and a stop time as optional arguments. When I remember right, there are problems with this function in org 8.2 but it works in org 8.3.3. I am not sure about that. The overall consequence is that you should also report youremacs-versionand yourorg-version.
