public abstract ChronoZonedDateTime<D> withZoneSameInstant (ZoneId zone)

Returns a copy of this date-time with a different time-zone, retaining the instant.

This method changes the time-zone and retains the instant. This normally results in a change to the local date-time.

This method is based on retaining the same instant, thus gaps and overlaps in the local time-line have no effect on the result.

To change the offset while keeping the local time, use withZoneSameLocal(ZoneId).

zone    the time-zone to change to, not null

Returns:  a ChronoZonedDateTime based on this date-time with the requested zone, not null

DateTimeException    if the result exceeds the supported date range
