description: Tests that Temporal.TimeZone meets the requirements for built-in objects
 | 
						|
info: |
 | 
						|
    Unless specified otherwise, a built-in object that is callable as a function is a built-in
 | 
						|
    function object with the characteristics described in 10.3. Unless specified otherwise, the
 | 
						|
    [[Extensible]] internal slot of a built-in object initially has the value true.
 | 
						|
 | 
						|
    Unless otherwise specified every built-in function and every built-in constructor has the
 | 
						|
    Function prototype object [...] as the value of its [[Prototype]] internal slot.
