Description
The functx:timezone-from-duration function accepts an xs:dayTimeDuration and converts it to a timezone value (formatted as it appears in xs:date, xs:time, xs:dateTime etc. values). The dayTimeDuration may only have the hours (H) component (or the seconds component if the value is PT0S) and must be between -PT14H and PT14H inclusive.
