怎样解决ajax在解析json数据时单位秒的形式

@ResponseBody//获取包含了分页后的产品信息
@RequestMapping(value = "/userSelect/paging", produces = "text/html;charset=UTF-8")
public String userSelectPaging(String goPage, HttpSession session) {
    int page;
    if (goPage.equals(""))
        page = 0;
    else
        page = Integer.parseInt(goPage);
    Sort sort = new Sort(Sort.Direction.DESC, "createDate");
    Pageable pageable = new PageRequest(page, 10, sort);
    Page<user> users = userService.findAll(pageable, session);
    return JSON.toJSONString(users, true);
}</user>

function fmtDate(inputTime) {
       var date = new Date(inputTime);
       var y = date.getFullYear();
       var m = date.getMonth() + 1;
       m = m < 10 ? (&#39;0&#39; + m) : m;
       var d = date.getDate();
       d = d < 10 ? (&#39;0&#39; + d) : d;
       var h = date.getHours();
       h = h < 10 ? (&#39;0&#39; + h) : h;
       var minute = date.getMinutes();
       var second = date.getSeconds();
       minute = minute < 10 ? (&#39;0&#39; + minute) : minute;
       second = second < 10 ? (&#39;0&#39; + second) : second;
       return y + &#39;-&#39; + m + &#39;-&#39; + d + &#39; &#39; + h + &#39;:&#39; + minute + &#39;:&#39; + second;
   }
