Use
This SWI can be used to determine when DST starts and stops for a given year.
Notes
The returned time values will be within the indicated year. Depending on the territory, this may result in the end time being before the start time; e.g. territories in the southern hemisphere.
An error will be returned if the territory module does not have sufficient knowledge of the DST rules for the indicated year (error &197, “No rule for given timezone”)
This SWI was introduced in TerritoryManager 0.47
