Function mz_expr::scalar::func::timezone_interval_timestamptz

fn timezone_interval_timestamptz(
    a: Datum<'_>,
    b: Datum<'_>
) -> Result<Datum<'static>, EvalError>

Converts the UTC timestamptz datum b, to the local timestamp of the timezone datum a. The interval is not allowed to hold months, but there are no limits on the amount of seconds. The interval acts like a chrono::FixedOffset, without the -86,400 < x < 86,400 limitation.
