How do I format date in jQuery datetimepicker?

Here you go.

$('#timePicker').datetimepicker({
   // dateFormat: 'dd-mm-yy',
   format:'DD/MM/YYYY HH:mm:ss',
    minDate: getFormattedDate(new Date())
});

function getFormattedDate(date) {
    var day = date.getDate();
    var month = date.getMonth() + 1;
    var year = date.getFullYear().toString().slice(2);
    return day + '-' + month + '-' + year;
}

You need to pass datepicker() the date formatted correctly.
