Remarks
Returns a copy of this formatter with a new override chronology.
This returns a formatter with similar state to this formatter but with the override chronology set. By default, a formatter has no override chronology, returning null.
If an override is added, then any date that is formatted or parsed will be affected.
When formatting, if the temporal object contains a date, then it will be converted to a date in the override chronology. Whether the temporal contains a date is determined by querying the ChronoField#EPOCH_DAY EPOCH_DAY field. Any time or zone will be retained unaltered unless overridden.
If the temporal object does not contain a date, but does contain one or more ChronoField date fields, then a DateTimeException is thrown. In all other cases, the override chronology is added to the temporal, replacing any previous chronology, but without changing the date/time.
When parsing, there are two distinct cases to consider. If a chronology has been parsed directly from the text, perhaps because DateTimeFormatterBuilder#appendChronologyId() was used, then this override chronology has no effect. If no zone has been parsed, then this override chronology will be used to interpret the ChronoField values into a date according to the date resolving rules of the chronology.
This instance is immutable and unaffected by this method call.
