Inherited Summary

From class ZoneRules
public static	of(offset: ZoneOffset): ZoneRules Obtains an instance of {@code ZoneRules} that always uses the same offset.
public	isFixedOffset(): boolean Checks of the zone rules are fixed, such that the offset never varies.
public	isValidOffset(localDateTime: LocalDateTime, offset: ZoneOffset): boolean Checks if the offset date-time is valid for these rules.
public	offset(instantOrLocalDateTime: *): ZoneOffset
public	offsetOfInstant(instant: Instant): ZoneOffset Gets the offset applicable at the specified instant in these rules.
public	offsetOfLocalDateTime(localDateTime: LocalDateTime): ZoneOffset Gets a suitable offset for the specified local date-time in these rules.

boolean

public isFixedOffset(): boolean source

Override:

ZoneRules#isFixedOffset

Return:

boolean

public isValidOffset(dateTime: LocalDateTime, offset: ZoneOffset): boolean source

Override:

ZoneRules#isValidOffset

Params:

Name	Type	Attribute	Description
dateTime	LocalDateTime
offset	ZoneOffset

Return:

boolean

public offsetOfInstant(instant: Instant): ZoneOffset source

Override:

ZoneRules#offsetOfInstant

Params:

Name	Type	Attribute	Description
instant	Instant

Return:

ZoneOffset

public offsetOfLocalDateTime(localDateTime: LocalDateTime): ZoneOffset source

This implementation is NOT returning the best value in a gap or overlap situation as specified at ZoneRules.offsetOfLocalDateTime.

The calculated offset depends Date.prototype.getTimezoneOffset and its not specified at the ECMA-262 specification how to handle daylight savings gaps/ overlaps.

The Chrome Browser version 49 is returning the next transition offset in a gap/overlap situation, other browsers/ engines might do it in the same way.

Override:

ZoneRules#offsetOfLocalDateTime

Params:

Name	Type	Attribute	Description
localDateTime	LocalDateTime
