    var date = new Date('06/01/2020 00:20:00');
    dateTimeC2(date)
    console.log('%c Case 3', 'color:red');

    dateTimeC2(date)
    function dateTimeC2(date) {
        var dt = date;
        dt.setMinutes(00, 00, 00);
        console.log('start time ', dt.toLocaleTimeString());
        dt.setTime(dt.getTime() + (1 * 60 * 60 * 1000))
