if (month < 10) month = "0" + month;
if (date < 10) date = "0" + date;
if (hour < 10) hour = "0" + hour;
if (minu < 10) minu = "0" + minu;
if (sec < 10) sec = "0" + sec;
if (MS < 100)MS = "0" + MS;
var arr_week = new Array("星期日", "星期一", "星期二", "星期三", "星期四", "星期五", "星期六");
week = arr_week[day];
var time = "";
time = year + "年" + month + "月" + date + "日" + " " + hour + ":" + minu + ":" + sec + " " + week;
