<%= DoDateTime((rs.Fields.Item("n_date").value), 4, 1033) %>
请问其中的4,1003分别是什么意思，在ASP中显示日期或时间的时候，分别是如何设定格式的，
当代码是：<%= DoDateTime((rs.Fields.Item("n_date").value), 4, 1033) %>时，显示正常。
图片如下：

而当代码变成：<%= DoDateTime((rs.Fields.Item("n_date").value), 2, -1) %>
时，显示不正常，如下：
图片如下：

请高手指教。

请问该如何定义，我的这个代码如下：
<SCRIPT RUNAT=SERVER LANGUAGE=VBSCRIPT>                    
function DoDateTime(str, nNamedFormat, nLCID)                
    dim strRet                                
    dim nOldLCID                                
                                        
    strRet = str                                
    If (nLCID > -1) Then                            
        oldLCID = Session.LCID                        
    End If                                    
                                        
    On Error Resume Next                            
                                        
    If (nLCID > -1) Then                            
        Session.LCID = nLCID                        
    End If                                    
                                        
    If ((nLCID < 0) Or (Session.LCID = nLCID)) Then                
        strRet = FormatDateTime(str, nNamedFormat)            
    End If                                    
                                        
    If (nLCID > -1) Then                            
        Session.LCID = oldLCID                        
    End If                                    
                                        
    DoDateTime = strRet                            
End Function                                    
</SCRIPT>
有什么错的地方没？
