Adjusts the specified temporal object to have the same offset as this object.
Adjusts the specified temporal object to have the same offset as this object.
This returns a temporal object of the same observable type as the input with the offset changed to be the same as this.
The adjustment is equivalent to using Temporal#with(TemporalField, long)
passing ChronoField#OFFSET_SECONDS as the field.
In most cases, it is clearer to reverse the calling pattern by using
Temporal#with(TemporalAdjuster):
// these two lines are equivalent, but the second approach is recommended temporal = thisOffset.adjustInto(temporal); temporal = temporal.with(thisOffset);
This instance is immutable and unaffected by this method call.

Compares this offset to another offset in descending order.
Compares this offset to another offset in descending order.
The offsets are compared in the order that they occur for the same time
of day around the world. Thus, an offset of +10:00 comes before an
offset of +09:00 and so on down to -18:00.
The comparison is "consistent with equals", as defined by Comparable.

the comparator value, negative if less, postive if greater

Checks if this offset is equal to another offset.
Checks if this offset is equal to another offset.
The comparison is based on the amount of the offset in seconds. This is equivalent to a comparison by ID.
the object to check, null returns false
true if this is equal to the other offset
Gets the value of the specified field from this offset as an int.
Gets the value of the specified field from this offset as an int.
This queries this offset for the value for the specified field. The returned value will always be within the valid range of values for the field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.
If the field is a ChronoField then the query is implemented here.
The OFFSET_SECONDS field returns the value of the offset.
All other ChronoField instances will throw a DateTimeException.
If the field is not a ChronoField, then the result of this method
is obtained by invoking TemporalField.getFrom(TemporalAccessor)
passing this as the argument. Whether the value can be obtained,
and what the value represents, is determined by the field.

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 #getId() full ID is returned.

Gets the normalized zone offset ID.
Gets the normalized zone offset ID.
The ID is minor variation to the standard ISO-8601 formatted string for the offset. There are three formats:
Z - for UTC (ISO-8601) +hh:mm or -hh:mm - if the seconds are zero (ISO-8601) +hh:mm:ss or -hh:mm:ss - if the seconds are non-zero (not ISO-8601)the zone offset ID, not null
Gets the value of the specified field from this offset as a long.
Gets the value of the specified field from this offset as a long.
This queries this offset for the value for the specified field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.
If the field is a ChronoField then the query is implemented here.
The OFFSET_SECONDS field returns the value of the offset.
All other ChronoField instances will throw a DateTimeException.

Gets the associated time-zone rules.
Gets the associated time-zone rules.
The rules will always return this offset when queried. The implementation class is immutable, thread-safe and serializable.

Gets the total zone offset in seconds.
Gets the total zone offset in seconds.
This is the primary way to access the offset amount. It returns the total of the hours, minutes and seconds fields as a single offset that can be added to a time.

Checks if the specified field is supported.
Checks if the specified field is supported.
This checks if this offset can be queried for the specified field.
If false, then calling the #range(TemporalField) range and
#get(TemporalField) get methods will throw an exception.
If the field is a ChronoField then the query is implemented here.
The OFFSET_SECONDS field returns true.
All other ChronoField instances will return false.
If the field is not a ChronoField, then the result of this method
is obtained by invoking TemporalField.isSupportedBy(TemporalAccessor)
passing this as the argument.
Whether the field is supported is determined by the field.
the field to check, null returns false
true if the field is supported on this offset, false if not
Normalizes the time-zone ID, returning a ZoneOffset where possible.
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.

Queries this offset using the specified query.
Queries this offset using the specified query.
This queries this offset using the specified query strategy object.
The TemporalQuery object defines the logic to be used to
obtain the result. Read the documentation of the query to understand
what the result of this method will be.
The result of this method is obtained by invoking the
TemporalQuery#queryFrom(TemporalAccessor) method on the
specified query passing this as the argument.

Gets the range of valid values for the specified field.
Gets the range of valid values for the specified field.
The range object expresses the minimum and maximum valid values for a field. This offset is used to enhance the accuracy of the returned range. If it is not possible to return the range, because the field is not supported or for some other reason, an exception is thrown.
If the field is a ChronoField then the query is implemented here.
The #isSupported(TemporalField) supported fields will return
appropriate range instances.
All other ChronoField instances will throw a DateTimeException.
If the field is not a ChronoField, then the result of this method
is obtained by invoking TemporalField.rangeRefinedBy(TemporalAccessor)
passing this as the argument.
Whether the range can be obtained is determined by the field.

A time-zone offset from Greenwich/UTC, such as
+02:00.A time-zone offset is the period of time that a time-zone differs from Greenwich/UTC. This is usually a fixed number of hours and minutes.
Different parts of the world have different time-zone offsets. The rules for how offsets vary by place and time of year are captured in the
ZoneIdclass.For example, Paris is one hour ahead of Greenwich/UTC in winter and two hours ahead in summer. The
ZoneIdinstance for Paris will reference twoZoneOffsetinstances - a+01:00instance for winter, and a+02:00instance for summer.In 2008, time-zone offsets around the world extended from -12:00 to +14:00. To prevent any problems with that range being extended, yet still provide validation, the range of offsets is restricted to -18:00 to 18:00 inclusive.
This class is designed for use with the ISO calendar system. The fields of hours, minutes and seconds make assumptions that are valid for the standard ISO definitions of those fields. This class may be used with other calendar systems providing the definition of the time fields matches those of the ISO calendar system.
Instances of
ZoneOffsetmust be compared using#equals. Implementations may choose to cache certain common offsets, however applications must not rely on such caching.Specification for implementors
