JS转换JSON格式时间

JSON格式：

"drvierDate"：{"date":9,"day":6,"hours":16,"minutes":30,"month":7,"nanos":0,"seconds":0,"time":1407573000000,"timezoneOffset":-480,"year":114}

　　toDate(drvierDate)

function toDate(obj){
var date = new Date();
date.setTime(obj.time);
date.setHours(obj.hours);
date.setMinutes(obj.minutes);
date.setSeconds(obj.seconds);
return date.format("yyyy-MM-dd hh:mm:ss"); //调用<span style="font-family: Arial, Helvetica, sans-serif;">Date.prototype.format方法
</span>}

Date.prototype.format = function(format) {
 /*

　*　时间格式
  * format="yyyy-MM-dd hh:mm:ss";　
  */
 var o = {
  "M+" : this.getMonth() + 1,
  "d+" : this.getDate(),
  "h+" : this.getHours(),
  "m+" : this.getMinutes(),
  "s+" : this.getSeconds(),
  "q+" : Math.floor((this.getMonth() + 3) / 3),
  "S" : this.getMilliseconds()
 }
 if (/(y+)/.test(format)) {
  format = format.replace(RegExp.$1, (this.getFullYear() + "").substr(4
      - RegExp.$1.length));
 }
 for (var k in o) {
