what is the relationship between skip_off_time, work_time?

Hi,

I have set work_time and skip_off_time as true,to skip the week end days in the grid but the gantt is not doing that. But if set skip_off_time to false then it is working correctly. So what is the purpose of skip_off_time

If you set the work_time to true and skip_off_time to false then, gantt will show the only working hours specified with gantt.setWorkTime({ hours:[7,16] })
