description: An IANA timezone code for the timezone offset per BCP 175.\nFor data types allowing the offset (all except date and time), this extension SHALL agree with the offset if provided and cannot be used in place of the offset if the precision expressed requires an offset.  Where an offset is provided, this extension provides a more legible display of the zone associated with the offset.  Where an offset is not present, this extension can be used to provide zone information not otherwise available.
