The ISO date formatter that formats or parses a date with the
offset if available, such as '2011-12-03' or '2011-12-03+01:00'.
!(p)
This returns an immutable formatter capable of formatting and parsing
the ISO-8601 extended date format.
The format consists of:
!(ul)
!(li)The {@link #ISO_LOCAL_DATE}
!(li)If the offset is not available then the format is complete.
!(li)The {@link ZoneOffset#getId() offset ID}. If the offset has seconds then
they will be handled even though this is not part of the ISO-8601 standard.
Parsing is case insensitive.
</ul>
!(p)
As this formatter has an optional element, it may be necessary to parse using
{@link DateTimeFormatter#parseBest}.
!(p)
The returned formatter has a chronology of ISO set to ensure dates _in
other calendar systems are correctly converted.
It has no override zone and uses the {@link ResolverStyle#STRICT STRICT} resolver style.
