上传文件时，怎样让上传后的文件名为当前时间(年月日时分秒)

[fkueyga6]

Ft_admin_upload.asp代码如下：
<!--#include file="Ft_config.asp"-->
<form name="up" method="post" action="Ft_admin_upfile.asp" enctype="multipart/form-data" onSubmit="return chk1();">
<input name="img" type="file" size="10"> <input type="submit" name="submit2" value="上传" class="submit">
<span class="STYLE1">只能上传30K大小的文件(规格约为100×100)</span>
</form>

Ft_config.asp代码如下：
<%
'====="上传设置"=====
Const allowupfile="gif;txt;jpg;jpeg;png;bmp;rar;zip" '各扩展名以英文分号分隔！系统默认允许文件列表为：gif;txt;jpg;jpeg;png;bmp;rar;zip;txt
Const allowupfilesize=30720 '上传文件大小设置，单位为：KB，注意不能设置过大，WIN2003有200K上传大小限制
%>

Ft_admin_upfile.asp代码如下：
<!--#include file="Ft_admin_upfile_class.asp"-->
<%
dim upfile,upmax,updir,checkupfile,SaveFilename
'==================================
'=参数设置：
'upmax为上传文件大小，此处设置为300KB，计算方法为 307200/1024=300K，注意不能过大，否则影响后面的自动检测功能；
'updir为上传目录，按月分别建立，总目录在程序根目录下的FUploadFile中；
'checkupfile为检测函数使用开关，0为关闭，1为启用
'==================================
'upmax=307200

updir="FUploadFile/"
checkupfile=1 '检测函数使用开关，0为关闭，1为启用

Dim chk
set chk = Server.CreateObject("Scripting.FileSystemObject")

end if
set chk=nothing
'执行保存文件代码
dim path,FSPath
FSPath=GetFilePath(Server.mappath("upfile.asp"),"\")'取得当前文件在服务器路径

楼上正解

[Quote=引用 2 楼 gentle_sword 的回复:]
楼上正解
[/Quote]
什么楼上正解？那也是我发的代码，正在用的代码

[fkueyga6]

这些代码在保存的时候只保存为原文件名，所以才提问的
