# ZoneOffset

public final class **ZoneOffset** extends [ZoneId](https://developers.google.com/j2objc/javadoc/jre/reference/java/time/ZoneId.html)  
implements [TemporalAccessor](https://developers.google.com/j2objc/javadoc/jre/reference/java/time/temporal/TemporalAccessor.html) [TemporalAdjuster](https://developers.google.com/j2objc/javadoc/jre/reference/java/time/temporal/TemporalAdjuster.html) [Comparable](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Comparable.html)\<[ZoneOffset](https://developers.google.com/j2objc/javadoc/jre/reference/java/time/ZoneOffset.html)\> [Serializable](https://developers.google.com/j2objc/javadoc/jre/reference/java/io/Serializable.html) A time-zone offset from Greenwich/UTC, such as `+02:00`.


A time-zone offset is the amount 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
`https://developers.google.com/j2objc/javadoc/jre/reference/java/time/ZoneId.html` class.


For example, Paris is one hour ahead of Greenwich/UTC in winter and two hours
ahead in summer. The `ZoneId` instance for Paris will reference two
`ZoneOffset` instances - a `+01:00` instance for winter,
and a `+02:00` instance 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 `ZoneOffset` must be compared using `https://developers.google.com/j2objc/javadoc/jre/reference/java/time/ZoneOffset.html#equals(java.lang.Object)`.
Implementations may choose to cache certain common offsets, however
applications must not rely on such caching.

## Fields

#### public static final ZoneOffset
**MAX**

Constant for the maximum supported offset.

#### public static final ZoneOffset
**MIN**

Constant for the maximum supported offset.

#### public static final ZoneOffset
**UTC**

The time-zone offset for UTC, with an ID of 'Z'.

## Public Methods

#### public [Temporal](https://developers.google.com/j2objc/javadoc/jre/reference/java/time/temporal/Temporal.html)
**adjustInto**
([Temporal](https://developers.google.com/j2objc/javadoc/jre/reference/java/time/temporal/Temporal.html) temporal)

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 `https://developers.google.com/j2objc/javadoc/jre/reference/java/time/temporal/Temporal.html#with(java.time.temporal.TemporalField,%20long)`
passing `https://developers.google.com/j2objc/javadoc/jre/reference/java/time/temporal/ChronoField.html#OFFSET_SECONDS` as the field.


In most cases, it is clearer to reverse the calling pattern by using
`https://developers.google.com/j2objc/javadoc/jre/reference/java/time/temporal/Temporal.html#with(java.time.temporal.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.

##### Parameters

| temporal | the target object to be adjusted, not null |
|---|---|

##### Returns

- the adjusted object, not null

##### Throws

| [DateTimeException](https://developers.google.com/j2objc/javadoc/jre/reference/java/time/DateTimeException.html) | if unable to make the adjustment |
| [ArithmeticException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/ArithmeticException.html) | if numeric overflow occurs |
|---|---|

#### public int
**compareTo**
([ZoneOffset](https://developers.google.com/j2objc/javadoc/jre/reference/java/time/ZoneOffset.html) other)

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 `https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Comparable.html`.

##### Parameters

| other | the other date to compare to, not null |
|---|---|

##### Returns

- the comparator value, negative if less, postive if greater

##### Throws

| [NullPointerException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/NullPointerException.html) | if `other` is null |
|---|---|

#### public boolean
**equals**
([Object](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/Object.html) obj)

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.

##### Parameters

| obj | the object to check, null returns false |
|---|---|

##### Returns

- true if this is equal to the other offset

#### public static [ZoneOffset](https://developers.google.com/j2objc/javadoc/jre/reference/java/time/ZoneOffset.html)
**from**
([TemporalAccessor](https://developers.google.com/j2objc/javadoc/jre/reference/java/time/temporal/TemporalAccessor.html) temporal)

Obtains an instance of `ZoneOffset` from a temporal object.


This obtains an offset based on the specified temporal.
A `TemporalAccessor` represents an arbitrary set of date and time information,
which this factory converts to an instance of `ZoneOffset`.


A `TemporalAccessor` represents some form of date and time information.
This factory converts the arbitrary temporal object to an instance of `ZoneOffset`.


The conversion uses the `https://developers.google.com/j2objc/javadoc/jre/reference/java/time/temporal/TemporalQueries.html#offset()` query, which relies
on extracting the `https://developers.google.com/j2objc/javadoc/jre/reference/java/time/temporal/ChronoField.html#OFFSET_SECONDS` field.


This method matches the signature of the functional interface `https://developers.google.com/j2objc/javadoc/jre/reference/java/time/temporal/TemporalQuery.html`
allowing it to be used as a query via method reference, `ZoneOffset::from`.

##### Parameters

| temporal | the temporal object to convert, not null |
|---|---|

##### Returns

- the zone-offset, not null

##### Throws

| [DateTimeException](https://developers.google.com/j2objc/javadoc/jre/reference/java/time/DateTimeException.html) | if unable to convert to an `ZoneOffset` |
|---|---|

#### public int
**get**
([TemporalField](https://developers.google.com/j2objc/javadoc/jre/reference/java/time/temporal/TemporalField.html) field)

Gets the value of the specified field from this offset as an `int`.


This queries this offset for the value of 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 `https://developers.google.com/j2objc/javadoc/jre/reference/java/time/temporal/ChronoField.html` then the query is implemented here.
The `OFFSET_SECONDS` field returns the value of the offset.
All other `ChronoField` instances will throw an `UnsupportedTemporalTypeException`.


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.

##### Parameters

| field | the field to get, not null |
|---|---|

##### Returns

- the value for the field

##### Throws

| [DateTimeException](https://developers.google.com/j2objc/javadoc/jre/reference/java/time/DateTimeException.html) | if a value for the field cannot be obtained or the value is outside the range of valid values for the field |
| [UnsupportedTemporalTypeException](https://developers.google.com/j2objc/javadoc/jre/reference/java/time/temporal/UnsupportedTemporalTypeException.html) | if the field is not supported or the range of values exceeds an `int` |
| [ArithmeticException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/ArithmeticException.html) | if numeric overflow occurs |
|---|---|

#### public [String](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/String.html)
**getId**
()

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)

#### public long
**getLong**
([TemporalField](https://developers.google.com/j2objc/javadoc/jre/reference/java/time/temporal/TemporalField.html) field)

Gets the value of the specified field from this offset as a `long`.


This queries this offset for the value of 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 `https://developers.google.com/j2objc/javadoc/jre/reference/java/time/temporal/ChronoField.html` then the query is implemented here.
The `OFFSET_SECONDS` field returns the value of the offset.
All other `ChronoField` instances will throw an `UnsupportedTemporalTypeException`.


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.

##### Parameters

| field | the field to get, not null |
|---|---|

##### Returns

- the value for the field

##### Throws

| [DateTimeException](https://developers.google.com/j2objc/javadoc/jre/reference/java/time/DateTimeException.html) | if a value for the field cannot be obtained |
| [UnsupportedTemporalTypeException](https://developers.google.com/j2objc/javadoc/jre/reference/java/time/temporal/UnsupportedTemporalTypeException.html) | if the field is not supported |
| [ArithmeticException](https://developers.google.com/j2objc/javadoc/jre/reference/java/lang/ArithmeticException.html) | if numeric overflow occurs |

##### Returns

- the rules, not null

#### public int
**getTotalSeconds**
()

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.

##### Returns

- the total zone offset amount in seconds

#### public int
**hashCode**
()

A hash code for this offset.

##### Returns

- a suitable hash code

#### public boolean
**isSupported**
([TemporalField](https://developers.google.com/j2objc/javadoc/jre/reference/java/time/temporal/TemporalField.html) field)

Checks if the specified field is supported.


This checks if this offset can be queried for the specified field.
If false, then calling the `https://developers.google.com/j2objc/javadoc/jre/reference/java/time/ZoneOffset.html#range(java.time.temporal.TemporalField)` and
`https://developers.google.com/j2objc/javadoc/jre/reference/java/time/ZoneOffset.html#get(java.time.temporal.TemporalField)` methods will throw an exception.


If the field is a `https://developers.google.com/j2objc/javadoc/jre/reference/java/time/temporal/ChronoField.html` 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.

##### Parameters

| field | the field to check, null returns false |
|---|---|

##### Returns

- true if the field is supported on this offset, false if not
