During the time of requesting ODatatype - DateTimeOffset from the from the following service - http://services.odata.org/V4/Northwind/Northwind.svc/

Query - Select * from Employees.

Using the above query it is unable to return DateTimeOffset values for it and returns the
following error -

From the initial level analysis and observation is has been observed teiid class - ODataTypeManager in that parselitreals method where ODatatype.Substring(4) is done which is causing the issue which is changing DateTimeOffset to TimeOffset and when it tries to find the Enum constant from the EdmPrimitiveTypeKind list it is unable find the changed name and this seems to be causing the issue in accessing the DateTimeOffset type datas from the containing tables.
