Thank you. Some comments follow.

TINYCHANGE is only about the number of non-trivial lines of code in your
patch (15 or so).

The name of the function is wrong, it should start with "org-clock".
Also, docstring's first line must contain a full sentence.

Anyway, this is used only once in your patch, I suggest to inline in

See above about inlining.

Would you mind adding an ORG-NEWS entry, and, if possible, writing
a test?
