+  Intl.supportedValuesOf ( key )

+  1. Let key be ? ToString(key).
+  ...
+  6. Else if key is "timeZone", then
+    a. Let list be ! AvailableTimeZones( ).
+  ...
+  9. Return ! CreateArrayFromList( list ).
+
+  AvailableTimeZones ()
+    The AvailableTimeZones abstract operation returns a sorted List of supported
+    Zone and Link names in the IANA Time Zone Database. The following steps are
+    taken:
+
+    1. Let names be a List of all supported Zone and Link names in the IANA Time
+       Zone Database.
+    2. Let result be a new empty List.
+    3. For each element name of names, do
+        a. Assert: ! IsValidTimeZoneName( name ) is true.
+        b. Let canonical be ! CanonicalizeTimeZoneName( name ).
+        c. If result does not contain an element equal to canonical, then
+            i. Append canonical to the end of result.
+    4. Sort result in order as if an Array of the same values had been sorted using
+       %Array.prototype.sort% using undefined as comparefn.
+    5. Return result.
