Returns a copy of this formatter with a new override chronology.
!(p)
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.
!(p)
If an override is added, then any date that is formatted or parsed will be affected.
!(p)
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
{@link ChronoField#EPOCH_DAY EPOCH_DAY} field.
Any time or zone will be retained unaltered unless overridden.
!(p)
If the temporal object does not contain a date, but does contain one
or more {@code ChronoField} date fields, then a {@code 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.
!(p)
When parsing, there are two distinct cases to consider.
If a chronology has been parsed directly from the text, perhaps because
{@link 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 {@code ChronoField} values into a date according to the
date resolving rules of the chronology.
!(p)
This instance is immutable and unaffected by this method call.
