If you do not want the time of input of date

Hi, thanks for your answer...

The display of the task to be a day, it was found that you must do the following.
      start: new Date("2016/2/15"),
      end: new Date("2016/2/16")

But in my Gantt chart input per day (start: 2016/2/15 end: 2016/2/15) was at the time, want to bar display of tasks per day.
Internally start: 2016/2/15 end: 2016/2/16 set the, Is it possible to display the "Task Edit Panel" and "Columns" and "Tooltip" in 2016/2/15?
