This function may help you to change the date to YYYY-MM-DD format.You can change the format by just changing the string in the datestring varible

function generateDateString(dateObj) {
    //convert date to specific format
    var date = dateObj;
    log.debug("date", date)
    var d = date.getDate();
    log.debug("d", d);
    var m = date.getMonth() + 1;
    log.debug("Month: ", m)
    var y = date.getFullYear()
    log.debug("Year: ", y)
    var dateString = (y + '-' + (m <= 9 ? '0' + m : m) + '-' + (d <= 9 ? '0' + d : d));
    log.debug("datestring: ", dateString);
