the lag / skipping of the clock was not caused by faulty timer code on fluxbox's side but by the behavior and inner workings of time(). since this is fixed now (913244789f) we can now rollbackec7fe513c8and detect strftime-formats which need intervals of seconds or minutes. minor: the small change to FbTk::Timer::setTimeout() reduces one start() / stop() cycle for a running timer.
