Get the current date and clock time in a specific time zone, using the ISO 8601 calendar. Note that the `Temporal.PlainDateTime` type does not persist the time zone, but retaining the time zone is required for most time-zone-related use cases. Therefore, it's usually recommended to use `Temporal.Now.zonedDateTimeISO` instead of this function.
