final class ZoneRegion extends ZoneId with Serializable

A geographical region where the same time-zone rules apply.

Time-zone information is categorized as a set of rules defining when and how the offset from UTC/Greenwich changes. These rules are accessed using identifiers based on geographical regions, such as countries or states. The most common region classification is the Time Zone Database (TZDB), which defines regions such as 'Europe/Paris' and 'Asia/Tokyo'.

The region identifier, modeled by this class, is distinct from the underlying rules, modeled by ZoneRules. The rules are defined by governments and change frequently. By contrast, the region identifier is well-defined and long-lived. This separation also allows rules to be shared between regions if appropriate.

Specification for implementors

This class is immutable and thread-safe.

def getDisplayName(style: TextStyle, locale: Locale): String

Gets the textual representation of the zone, such as 'British Time' or '+02:00'.
Gets the textual representation of the zone, such as 'British Time' or '+02:00'.
This returns the textual name used to identify the time-zone ID, suitable for presentation to the user. The parameters control the style of the returned text and the locale.
If no textual mapping is found then the full ID is returned.

def getRules: ZoneRules

Gets the time-zone rules for this ID allowing calculations to be performed.
Gets the time-zone rules for this ID allowing calculations to be performed.
The rules provide the functionality associated with a time-zone, such as finding the offset for a given instant or local date-time.
A time-zone can be invalid if it is deserialized in a Java Runtime which does not have the same rules loaded as the Java Runtime that stored it. In this case, calling this method will throw a ZoneRulesException.
The rules are supplied by ZoneRulesProvider. An advanced provider may support dynamic updates to the rules without restarting the Java Runtime. If so, then the result of this method may change over time. Each individual call will be still remain thread-safe.
ZoneOffset will always return a set of rules where the offset never changes.

Normalizes the time-zone ID, returning a ZoneOffset where possible.
The returns a normalized ZoneId that can be used in place of this ID. The result will have ZoneRules equivalent to those returned by this object, however the ID returned by getId() may be different.
The normalization checks if the rules of this ZoneId have a fixed offset. If they do, then the ZoneOffset equal to that offset is returned. Otherwise this is returned.
