* instances that can produce a date, such as {@code EPOCH_DAY}.
* <p>
* Not all {@code TemporalAccessor} implementations are accepted as return values.
* Implementations that call this method must accept {@code ChronoLocalDate},
* {@code ChronoLocalDateTime}, {@code ChronoZonedDateTime} and {@code LocalTime}.
* <p>
* The default implementation must return null.

* @param FieldValues $fieldValues the map of fields to values, which can be updated, not null
* @param TemporalAccessor $partialTemporal the partially complete temporal to query for zone and
* chronology; querying for other things is undefined and not recommended, not null
* @param ResolverStyle $resolverStyle the requested type of resolve, not null
* @return TemporalAccessor the resolved temporal object; null if resolving only
* changed the map, or no resolve occurred
* @throws ArithmeticException if numeric overflow occurs
* @throws DateTimeException if resolving results in an error. This must not be thrown
* by querying a field on the temporal without first checking if it is supported
