/**
 * Obtains an instance of {@code ZonedDateTime} from a local date-time
 * using the preferred offset if possible.
 * <p>
 * The local date-time is resolved to a single instant on the time-line.
 * This is achieved by finding a valid offset from UTC/Greenwich for the local
 * date-time as defined by the {@link ZoneRules rules} of the zone ID.
 *<p>
 * In most cases, there is only one valid offset for a local date-time.
 * In the case of an overlap, where clocks are set back, there are two valid offsets.
 * If the preferred offset is one of the valid offsets then it is used.
 * Otherwise the earlier valid offset is used, typically corresponding to "summer".
 * <p>
 * In the case of a gap, where clocks jump forward, there is no valid offset.
 * Instead, the local date-time is adjusted to be later by the length of the gap.
 * For a typical one hour daylight savings change, the local date-time will be
 * moved one hour later into the offset typically corresponding to "summer".
 *
 * @param localDateTime  the local date-time, not null
 * @param zone  the time-zone, not null
 * @param preferredOffset  the zone offset, null if no preference
 * @return the zoned date-time, not null

 * ID.
 * <p>
 * In most cases, there is only one valid offset for a local date-time. In the case of an overlap, where
 * clocks are set back, there are two valid offsets. If the preferred offset is one of the valid offsets
 * then it is used. Otherwise the earlier valid offset is used, typically corresponding to "summer".
 * <p>
 * In the case of a gap, where clocks jump forward, there is no valid offset. Instead, the local date-time
 * is adjusted to be later by the length of the gap. For a typical one hour daylight savings change, the
 * local date-time will be moved one hour later into the offset typically corresponding to "summer".
