Example 1
private SortedSet<TimeUnit> findUnitsToDisplay(ExpectMaxExecutionTime annotation) {

        TimeUnit minUnitToDisplay = findMinUnitToDisplay(annotation);
        TimeUnit maxUnitToDisplay = findMaxUnitToDisplay(annotation);

        TreeSet<TimeUnit> timeUnits = new TreeSet<>();
        timeUnits.add(TimeUnit.HOURS);
        timeUnits.add(TimeUnit.MINUTES);
        timeUnits.add(TimeUnit.SECONDS);
        timeUnits.add(TimeUnit.MILLISECONDS);
        timeUnits.add(TimeUnit.MICROSECONDS);
        timeUnits.add(TimeUnit.NANOSECONDS);

        return timeUnits.subSet( minUnitToDisplay, true
                , maxUnitToDisplay, true);
