毫秒转时间(java.js)

1 SimpleDateFormat sdf = new SimpleDateFormat(
2                 "yyyy-MM-dd HH:mm:ss");
3         GregorianCalendar gc = new GregorianCalendar();
4         gc.setTimeInMillis(1421915508113l);
5 
6         Date time2 = gc.getTime();
7         String format = sdf.format(time2);
8         System.out.println(format);

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