Unable to update datetime in datetimepicker after setting mindate

[rajausman]

I have following Code:
// intialization
$('#datetimepicker2').datetimepicker({
minDate: moment().millisecond(0).second(0).minute(0).hour(0),
format: 'YYYY/MM/DD HH:mm A',

});

I have use minDate = 0 ,minDate=new Date(), minDate=moment() but didn't work :(
// update case when trigger Edit Button
function ChangeFormat(dates) {

var newDate = moment.utc(dates).local().format();
newDate = moment(newDate).format('YYYY/MM/DD  HH:mm A');
return newDate;

};
var date = ChangeFormat(UTCDateTime);

$('#datetimepicker2').data("DateTimePicker").date(date);

$("#updateSchedulemodal").modal('show');
