setTimeout takes a duration in ms, not a timestamp. If it did take a timestamp, I think you would need to pass it a timezone to disambiguate.
Maybe a better argument is, “when you’re setting a phone alarm, you don’t tell it a timezone.” Maybe the distinction is whether the timezone is established at write time or read time.
