In GramJob duration and terminationTime are handled separately.
Duration is handled currently in weird way.
If someone sets the job duration via GramJob only the hour of the
day and minutes are taken from the input type java.util.Date.
So a duration > 24h is not possible.
Also it does not seem to be very intuitive that the duration of a
job will e.g. be 17 hours if the time of the Date of the input
parameter 'duration' is 17:00:00

Here's code from an older version of trunk

    public void setDuration(
        Date duration)
    {
        if (duration == null)
        {
            this.terminationTime = null;
        }
        else
        {
            Calendar durationCalendar = Calendar.getInstance();
            durationCalendar.setTime(duration);
            int hours = durationCalendar.get(Calendar.HOUR_OF_DAY);
            int minutes = durationCalendar.get(Calendar.MINUTE);

            this.terminationTime = Calendar.getInstance();
            this.terminationTime.add(Calendar.HOUR_OF_DAY, hours);
            this.terminationTime.add(Calendar.MINUTE, minutes);
        }
    }

We'll change the setDuration method to the following:

    void setDuration(int hours, int minutes)

GramJob will then calculate the termination time by adding the hours
and minutes to the current date.

Implementation already completed.
