the idea (as a first patch) for this change was provided by Thomas Habets (thomas at habets pp se). instead of having a fixed interval each second, we now calculate the next point in time based upon the format string used by the clocktool to render the time. as long as no seconds are shown fluxbox now wakes up once every minute.
