Pull from NTP through proxy

[Simpel]

Hi, 

I tried a function by @kor here: 

But it does not work through a proxy. So I tried a bit. With some forum help months ago I had a www-solution through a proxy for some other stuff. But trying it with ntp didn't work.

#include <WinHttp.au3>
Global Const $sProxy = "http://prx01.xxx.de:8080"
Global Const $sUserName = "UserName", $sPassword = "PassWord"
$vOpen = _WinHttpOpen(Default, $WINHTTP_ACCESS_TYPE_NAMED_PROXY, $sProxy)
$vConnect = _WinHttpConnect($vOpen, "pool.ntp.org", 123) ; Port 123
$vRequest = _WinHttpSimpleSendRequest_ProxyAuth($vConnect)
Global $sSource = _WinHttpSimpleReadData($vRequest)
ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $sSource = ' & $sSource & @CRLF & '>Error code: ' & @error & @CRLF) ;### Debug Console
Exit

Func _WinHttpSimpleSendRequest_ProxyAuth($hConnect, $sType = Default, $sPath = Default, $sReferrer = Default, $sDta = Default, $sHeader = Default)
    Local $hRequest = _WinHttpSimpleSendRequest($hConnect, $sType, $sPath, $sReferrer, $sDta, $sHeader)
    If $hRequest Then
        Local $iStatusCode = _WinHttpQueryHeaders($hRequest, $WINHTTP_QUERY_STATUS_CODE)
        If $iStatusCode = $HTTP_STATUS_PROXY_AUTH_REQ Then
            Local $iSupportedSchemes, $iFirstScheme, $iAuthTarget ; Query Authorization scheme
            If _WinHttpQueryAuthSchemes($hRequest, $iSupportedSchemes, $iFirstScheme, $iAuthTarget) Then
                _WinHttpSetCredentials($hRequest, $iAuthTarget, $iFirstScheme, $sUserName, $sPassword) ; Set passed credentials
                _WinHttpSendRequest($hRequest)  ; Set passed credentials
                _WinHttpReceiveResponse($hRequest) ; And wait for the response again
            EndIf
        EndIf
    EndIf
    Return $hRequest
EndFunc

(This snippet only tries to get raw data.) 

$sSource is "". With no port (instead of 123) I only get the informations I see when I type url into a browser - so it's not the information I seek. (There is not time included in http source code.)

Some hints? Regards, Conrad
