/**
* Obtains an instance of {@code ZonedDateTime} from a temporal object.

* This obtains a zoned date-time based on the specified temporal.
* A {@code TemporalAccessor} represents an arbitrary set of date and time information,
* which this factory converts to an instance of {@code ZonedDateTime}.
* <p>
* The conversion will first obtain a {@code ZoneId} from the temporal object,
* falling back to a {@code ZoneOffset} if necessary. It will then try to obtain
* an {@code Instant}, falling back to a {@code LocalDateTime} if necessary.
* The result will be either the combination of {@code ZoneId} or {@code ZoneOffset}
* with {@code Instant} or {@code LocalDateTime}.
* Implementations are permitted to perform optimizations such as accessing
* those fields that are equivalent to the relevant objects.
* <p>
* This method matches the signature of the functional interface {@link TemporalQuery}
* allowing it to be used as a query via method reference, {@code ZonedDateTime::from}.
*
* @param TemporalAccessor $temporal the temporal object to convert, not null
* @return ZonedDateTime the zoned date-time, not null
