Why not just have an #else
    using OpaqueICUTimeZone = icu::Timezone;
here and avoid all the bitwise_cast, as well as remove some of the #if HAVE(ICU_C_TIMEZONE_API) below?

Ah, this does not work. using (typedef) and class forward declaration are different.

r=me.  Please make sure that the mac-AS-debug-wk2 bot failure is not real.

"The above" sounds wrong since there's no code that has any effect above.  How about changing it to "This function"?

This failed return value also seem to contradict the comment above the function which states that "If this function is called with NaN it returns NaN."  Maybe remove the comment above the function?

Thanks. And AS fail is media/media-fragments/TC0051.html, which is known flaky these days.

Yes, I've changed them.
