解决antd datepicker 获取时间默认少8个小时的问题

Date.prototype.format = function (fmt) {
 let o = {
  "M+": this.getMonth() + 1,         //月份
  "d+": this.getDate(),          //日
  "h+": this.getHours(),          //小时
  "m+": this.getMinutes(),         //分
  "s+": this.getSeconds(),         //秒
  "q+": Math.floor((this.getMonth() + 3) / 3), //季度
  "S": this.getMilliseconds()       //毫秒
 };
 if (/(y+)/.test(fmt)) {
  fmt = fmt.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
 }
 for (let k in o) {
  if (new RegExp("(" + k + ")").test(fmt)) {
   fmt = fmt.replace(RegExp.$1, (RegExp.$1.length === 1) ? (o[k]) : (("00" + o[k]).substr(("" + o[k]).length)));
  }
 }
 return fmt;
};
