Returns a copy of this ZonedDateTime, changing the zone offset to the earlier of the two valid offsets at a local time-line overlap. The overlap happens when DST period finishes and one hour is returned. In this scenario, there are two valid offsets for the local date-time. Calling this method will return a zoned date-time with the earlier of the two zones.
