Agent wirte Data(TImezone) Exception

When I try to write Clock Timezone data, the following error occurs on the Agent client

-----------------------------------------------------
fail: Gurux.DLMS.AMI.Agent.Worker.GXAgentWorker[0]
2024/5/10 15:59:22 Failed to execute task Write #3 started String '<Int16 Value="-480" />
' was not recognized as a valid DateTime. String '<Int16 Value="-480" />
' was not recognized as a valid DateTime.

-----------------------------------------------------------
I analyzed the Agent source code and found that when writing data, the Attr data type to be written was not set to the Object, but a default value was obtained. I guess it's this that causes the exception

The following is this code
------------------------------------------------------------
GXDLMSObject obj;
if (task.Object != null && task.Object.Template != null)
{
obj = GXDLMSClient.CreateObject((ObjectType)task.Object.Template.ObjectType);
obj.Version = task.Object.Template.Version.GetValueOrDefault(0);
obj.LogicalName = task.Object.Template.LogicalName;
obj.ShortName = task.Object.Template.ShortName.GetValueOrDefault();
}
else if (task.Attribute != null && task.Attribute.Object != null &&
task.Attribute.Object.Template != null)
{
if (task.Attribute.Object.Template.ObjectType == null)
{
throw new Exception("Invalid object type.");
}
obj = GXDLMSClient.CreateObject((ObjectType)task.Attribute.Object.Template.ObjectType);
// obj.Version = task.Object.Template.Version.GetValueOrDefault(0);
obj.LogicalName = task.Attribute.Object.Template.LogicalName;
obj.ShortName = task.Attribute.Object.Template.ShortName.GetValueOrDefault();
}
else if (task.Device?.Objects != null)
{
foreach (var it in task.Device.Objects)
{
task.Object = it;
await ExecuteTasks(dev, reader, cl, task);
}
return;
}
else
{
throw new ArgumentException("Invalid object.");
}
if (task.TaskType == TaskType.Write)
{
DataType dt = obj.GetDataType(2);
DataType uiDt = obj.GetUIDataType(2);
_logger?.LogInformation(DateTime.Now + " DataType: "+dt+ " , UIDataType: "+ uiDt);
//If date-time value is updated.
if (uiDt == DataType.DateTime ||
uiDt == DataType.Date ||
uiDt == DataType.Time)
{
if (dt == DataType.OctetString)
{
//If value is null currect date time is used.
if (string.IsNullOrEmpty(task.Data))
{
if (dt == DataType.OctetString || dt == DataType.DateTime || dt == DataType.Date || dt == DataType.Time)
{
cl.UpdateValue(obj, task.Index.GetValueOrDefault(0), DateTime.Now);
}
else
{
cl.UpdateValue(obj, task.Index.GetValueOrDefault(0), GXDateTime.ToUnixTime(DateTime.UtcNow));
}
}
else
{
if (uiDt == DataType.DateTime)
{
cl.UpdateValue(obj, task.Index.GetValueOrDefault(0), new GXDateTime(task.Data, CultureInfo.InvariantCulture));
}
else if (uiDt == DataType.Date)
{
cl.UpdateValue(obj, task.Index.GetValueOrDefault(0), new GXDate(task.Data, CultureInfo.InvariantCulture));
}
