That's exactly why Temporal uses RFC 9557 for its `ZonedDateTime` serialization format:

    >> zdt = Temporal.Now.zonedDateTimeISO()
    >> zdt.toJSON()
    "2025-01-24T19:57:01.089557834-05:00[America/New_York]"
    >> zdt.toString()
    "2025-01-24T19:57:01.089557834-05:00[America/New_York]"
Temporal will even check that the offset is still correct for the time zone when you deserialize.
