Converting a LocalDateTime to a ZonedDateTime using an IANA time‑zone identifier aims to produce the correct wall‑clock offset for the specified region. The conversion requires an explicit ZoneId; without it an exception is thrown and the offset depends on the TZ database version bundled with the JVM. Can the same ZoneId yield different offsets on Java versi
