Interface Chronology

public interface Chronology

Chronology provides access to the individual date time fields for a chronological calendar system.

Various chronologies are supported by subclasses including ISO and GregorianJulian. To construct a Chronology you should use the factory methods on the TimeSupportManager.

The provided chronology implementations are:

  • ISO - Based on the ISO8601 standard and suitable for use after about 1600
  • GJ - Historically accurate calendar with Julian followed by Gregorian
  • Gregorian - The Gregorian calendar system used for all time (proleptic)
  • Julian - The Julian calendar system used for all time (proleptic)
  • Buddhist - The Buddhist calendar system which is an offset in years from GJ
  • Coptic - The Coptic calendar system which defines 30 day months
  • Ethiopic - The Ethiopic calendar system which defines 30 day months

Instances of this class are singletons and they can be compared using the ChronologygetType() method and the == operator.

A huge part of the documentation of this class has been retrieved from the joda-time library.
