    • Method Detail

      • getZone

        public abstract DateTimeZone getZone()
        Returns the DateTimeZone that this Chronology operates in, or null if unspecified.
        Returns:
        the DateTimeZone, null if unspecified
      • withUTC

        public abstract Chronology withUTC()

        Returns:
        a version of this chronology that ignores time zones
      • withZone

        public abstract Chronology withZone(DateTimeZone zone)

      • getDateTimeMillis

        public abstract long getDateTimeMillis(int year,
                                               int monthOfYear,
                                               int dayOfMonth,

        Returns a datetime millisecond instant, formed from the given year, month, day, and millisecond values. The set of given values must refer to a valid datetime, or else an IllegalArgumentException is thrown.

        The default implementation calls upon separate DateTimeFields to determine the result. Subclasses are encouraged to provide a more efficient implementation.

                                               int millisOfSecond)
        Returns a datetime millisecond instant, formed from the given year, month, day, hour, minute, second, and millisecond values. The set of given values must refer to a valid datetime, or else an IllegalArgumentException is thrown.

        The default implementation calls upon separate DateTimeFields to determine the result. Subclasses are encouraged to provide a more efficient implementation.
