Appends the time-zone name, such as 'British Summer Time', to the formatter.
!(p)
This appends an instruction to format/parse the textual name of the zone to
the builder.
!(p)
During formatting, the zone is obtained using a mechanism equivalent
to querying the temporal with {@link TemporalQueries#zoneId()}.
If the zone is a {@code ZoneOffset} it will be printed using the
result of {@link ZoneOffset#getId()}.
If the zone is not an offset, the textual name will be looked up
for the locale set _in the {@link DateTimeFormatter}.
If the temporal object being printed represents an instant, or if it is a
local date-time that is not _in a daylight saving gap or overlap then
the text will be the summer or winter time text as appropriate.
If the lookup for text does not find any suitable result, then the
{@link ZoneId#getId() ID} will be printed.
If the zone cannot be obtained then an exception is thrown unless the
section of the formatter is optional.
!(p)
During parsing, either the textual zone name, the zone ID or the offset
is accepted. Many textual zone names are not unique, such as CST can be
for both "Central Standard Time" and "China Standard Time". In this
situation, the zone id will be determined by the region information from
formatter's {@link DateTimeFormatter#getLocale() locale} and the standard
zone id for that area, for example, America/New_York for the America Eastern
zone. The {@link #appendZoneText(TextStyle, Set)} may be used
to specify a set of preferred {@link ZoneId} _in this situation.
