The values requested using the Unicode extension keys "ca" and "nu" or filled in as default values.

The value provided for this property in the options argument; undefined (representing the runtime's default time zone) if none was provided. Warning: Applications should not rely on undefined being returned, as future versions may return a String value identifying the runtime’s default time zone instead.

timeZoneName
The values resulting from format matching between the corresponding properties in the options argument and the available combinations and representations for date-time formatting in the selected locale. Some of these properties may not be present, indicating that the corresponding components will not be represented in formatted output.
