TimeZoneFormat
supports time zone display name formatting and parsing.
An instance of TimeZoneFormat works as a subformatter of SimpleDateFormat, but you can also directly get a new instance of TimeZoneFormat
and formatting/parsing time zone display names.
ICU implements the time zone display names defined by UTS#35 Unicode Locale Data Markup Language (LDML). TimeZoneNames represents the time zone display name data model and this class implements the algorithm for actual formatting and parsing.
