Package org.joda.time.chrono

Class ISOChronology

  • All Implemented Interfaces:
    java.io.Serializable
    public final class ISOChronology
extends AssembledChronology
    Implements a chronology that follows the rules of the ISO8601 standard, which is compatible with Gregorian for all modern dates. When ISO does not define a field, but it can be determined (such as AM/PM) it is included.

    With the exception of century related fields, ISOChronology is exactly the same as GregorianChronology. In this chronology, centuries and year of century are zero based. For all years, the century is determined by dropping the last two digits of the year, ignoring sign. The year of century is the value of the last two year digits.

    ISOChronology is thread-safe and immutable.
