If the node supports a time zone database with information for the time zone that will be applied, it
may use this information to set the DSTOffset attribute. If the node is setting its own DSTOffset attribute, the DSTOffsetsRequired field shall be set to false, otherwise it shall be set to true.
This command shall be generated in response to a SetTimeZone command.
