title: How to prevent jQuery bootstrap ClockPicker to get minutes that are not divisible by 5
body: <p>I am using <a href="https://weareoutman.github.io/clockpicker/" rel="nofollow">jQuery bootstrap ClockPicker</a> and need to get only times that their minutes are divisible by 5. For example if user selects 13:08, the ClockPicker should select 13:05.</p>
  
  <p>Is there a way to override clockpicker to round down selected times minutes?</p>
