/**
* Obtains an instance of {@code ZonedDateTime} from a local date-time

* <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".
