  var nowTime = getLocalTime(timestamp);  //  2018/10/15 下午9:45

  //第二种
  function getLocalTime1(nS) {
    return new Date(parseInt(nS)).toLocaleString().substr(0, 17)
  }
  var nowTime = getLocalTime1(timestamp); // 2018/10/15 下午9:53

  //第三种
   function getLocalTime2(nS) {
    return new Date(parseInt(nS)).toLocaleString().replace(/年|月/g, "-").replace(/日/g, " ");
