毫秒转时间(java.js)

java：

SimpleDateFormat sdf = new SimpleDateFormat(                "yyyy-MM-dd HH:mm:ss");        GregorianCalendar gc = new GregorianCalendar();        gc.setTimeInMillis(1421915508113l);        Date time2 = gc.getTime();        String format = sdf.format(time2);        System.out.println(format);

js：

 var oldTime = (new Date("2011/11/11 20:10:10")).getTime(); //得到毫秒数 var newTime = new Date(oldTime); //就得到普通的时间了
