AbstractInstant (The Adobe AEM Quickstart and Web Application.)

java.lang.Object
- org.joda.time.base.AbstractInstant

All Implemented Interfaces:

java.lang.Comparable<ReadableInstant>, ReadableInstant

Direct Known Subclasses:

AbstractDateTime, Instant
```
public abstract class AbstractInstant
extends java.lang.Object
implements ReadableInstant
```
AbstractInstant provides the common behaviour for instant classes.
This class has no concept of a chronology, all methods work on the millisecond instant.
This class should generally not be used directly by API users. The ReadableInstant interface should be used when different kinds of date/time objects are to be referenced.
Whenever you want to implement ReadableInstant you should extend this class.
AbstractInstant itself is thread-safe and immutable, but subclasses may be mutable and not thread-safe.

  - getZone
```
public DateTimeZone getZone()
```
    Gets the time zone of the instant from the chronology.

  - get
```
public int get(DateTimeFieldType type)
```
    Get the value of one of the fields of a datetime using the chronology of the instant.
    This method uses the chronology of the instant to obtain the value. For example:

    Returns:
    
    the value of that field
    
    Throws:
    
    java.lang.IllegalArgumentException - if the field type is null
  - isSupported
```
public boolean isSupported(DateTimeFieldType type)
