title: sheetJS: How should the cell object look when you want to transform milliseconds to h:mm?
body: <p>Does someone have an idea how the cell object should look like when you want to transform a value in milliseconds to a duration format of h:mm?</p>
  
  <p>At the moment I have a cell object which looks like
  <code>{ t: 'n', v: value, z: 'h:mm' }</code>
  but it doesn't display the correct hour and minutes.</p>
