This returns a {@code ZonedDateTime} formed from this date-time at thespecified time-zone. The result will match this date-time as closely as possible. Time-zone rules, such as daylight savings, mean that not every local date-time is valid for the specified zone, thus the local date-time may be adjusted.
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.
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. This method uses the earlier offset typically corresponding to "summer".
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".
To obtain the later offset during an overlap, call {@link ZonedDateTime#withLaterOffsetAtOverlap()} on the result of this method.To throw an exception when there is a gap or overlap, use {@link ZonedDateTime#ofStrict(LocalDateTime,ZoneOffset,ZoneId)}. @param zone the time-zone to use, not null @return the zoned date-time formed from this date-time, not null
