WCF；时钟偏移--忽略自定义绑定配置

我们的客户也面临着同样困扰许多其他人的时钟偏移问题。

这些页面中的答案和进一步的网络搜索帮助很大，但我面临着另一个问题。

在本地计算机上调试时，我可以看到绑定的属性设置正确。但由于我不能在本地测试代码（我只有一个时钟），我必须将服务发布到测试服务器。然而，当我使用偏斜的时钟连接到服务时，我仍然会收到MessageSecurityException s。

我的第一个想法是，绑定在创建后会被修改，但我和这个项目的一位同事都确认，绑定只创建了一次，之后就不会被修改了。

我显然做错了[TM]。如果有人能澄清此事，我将不胜感激。提前谢谢。

这是创建绑定的代码：

WSHttpBinding binding = new WSHttpBinding();
binding.Security.Mode = SecurityMode.TransportWithMessageCredential;
binding.Security.Message.ClientCredentialType = MessageCredentialType.UserName;
// ... blah blah ...
// fix ongoing security
sbe.LocalClientSettings.DetectReplays = false;
sbe.LocalClientSettings.MaxClockSkew = TimeSpan.MaxValue;
sbe.LocalClientSettings.SessionKeyRenewalInterval = TimeSpan.MaxValue;
sbe.LocalServiceSettings.DetectReplays = false;
sbe.LocalServiceSettings.MaxClockSkew = TimeSpan.MaxValue;
sbe.LocalServiceSettings.SessionKeyRenewalInterval = TimeSpan.MaxValue;
// fix bootstrap security
SecureConversationSecurityTokenParameters sct = null;
if (sbe is SymmetricSecurityBindingElement)
{
    SecurityTokenParameters tokenParameters = 
((SymmetricSecurityBindingElement)sbe).ProtectionTokenParameters;
    if (tokenParameters is SecureConversationSecurityTokenParameters)
    {
        sct = tokenParameters as SecureConversationSecurityTokenParameters; 
    }
}
else if (sbe is TransportSecurityBindingElement)
{
    sct = sbe.EndpointSupportingTokenParameters
             .Endorsing
             .OfType<SecureConversationSecurityTokenParameters>()
             .FirstOrDefault();
}
else
{
    throw new ArgumentException("Binding has neiter a " +
       "SymmetricSecurityBindingElement nor " + 
       "TransportSecurityBindingElement");
}
SecurityBindingElement bootbe = sct.BootstrapSecurityBindingElement;
bootbe.LocalClientSettings.DetectReplays = false;
bootbe.LocalClientSettings.MaxClockSkew = TimeSpan.MaxValue;
bootbe.LocalClientSettings.SessionKeyRenewalInterval = TimeSpan.MaxValue;
bootbe.LocalServiceSettings.DetectReplays = false;
bootbe.LocalServiceSettings.MaxClockSkew = TimeSpan.MaxValue;
bootbe.LocalServiceSettings.SessionKeyRenewalInterval = TimeSpan.MaxValue;

这是我在服务跟踪日志中收到的异常的调用堆栈：
