Distributes the sleeping time of a script over the 24 hours of a day, so that at the zenith the max_time will be waited and 12 hours later 1 second will be waited. That gives to opportunity to set the zenit to the hour of the day that to least traffic will be expected (e.g. 3am). This could be interesting to any kind of long running scripts that…
