Yes. It has a local repo, so I assume the reporting program should be able
to do anything you could do from the command line.

The tricky part, associating the tester with a SHA has already been done.
See develop boost-root\tools\regression\src\report\common.cpp line 480.

You don't need to run regression tests. You only need to be able to run the
regression reporting, which is very easy. See
tools/regression/doc/reports.html. A run only takes a couple of minutes, so
testing moves quickly.

If you wrote a C++ function, it would be far easier, since the reporting is
done is C++. Stick the function in develop
boost-root\tools\regression\src\report\common.cpp, then after line 480 call
it something like this:

"Date: " <<
get_the_date_as_a_string_given_the_sha_as_a_string(run.revision) << "\n"

And you are done:-) You might want to pick a shorter name, of course.
