首先是插入超文本  然后帖进去以下的语句，注意符号一定要是英文状态下的，时分秒可以按照需求来删除

<script type="text/javascript">

var currentDate = new Date();

document.write("<span style='font-size:12px;'>"+currentDate.getFullYear() + "-"

+ (currentDate.getMonth()+1) + "-"

+ currentDate.getDate() + " "

+ currentDate.getHours() + ":"

+ currentDate.getMinutes()+":"

+ currentDate.getSeconds()

+ "</span>");

</script>
