You can use the Modified JavaScript value step to round time to the nearest hour using JS and then use the Select values step to format the date.

function roundToHour(date) {
  p = 60 * 60 * 1000; // milliseconds in an hour
  return new Date(Math.round(date.getTime() / p ) * p);
}

var new_dt = roundToHour(dt);

var new_dt_fmt = roundToHour(dt);
