I want to use `SeekBar` to pick time. I have startDate and endDate. Difference in time is set as `seekbar.max` (could be for example 850 minutes(int 850)). And I want to increment this progress by 15 minutes.

How can I setup that? I tried to setup `seekbar.incrementProgressBy(15)` but its not working, its still incrementing by 1 minute.

What I want to achieve is that if I have 30 minutes as max and I want to move thumb button, it will automatically move to the middle so first increment is basically 15 minutes (progress 50%).

Code:

```
    maxDurationInMins = (((maxDate.time/1000)-(minDate.time/1000)).toInt())/60

    seekBar.progress = 0
    seekBar.max = maxDurationInMins
    seekBar.incrementProgressBy(15)
    seekBar.setOnSeekBarChangeListener(object: SeekBar.OnSeekBarChangeListener{
        override fun onProgressChanged(p0: SeekBar?, progress: Int, p2: Boolean) {
            updateProgressData(progress)
        }
        override fun onStartTrackingTouch(p0: SeekBar?) {}
        override fun onStopTrackingTouch(p0: SeekBar?) {}
    })

```
