 * Support for time-zones and their rules.

 * </p>

 * <p>

 * Daylight Saving Time and Time-Zones are concepts used by Governments to alter local time.

 * This package provides support for time-zones, their rules and the resulting

 * gaps and overlaps in the local time-line typically caused by Daylight Saving Time.

 * </p>

 *

 * <h3>Package specification</h3>

 * <p>

 * Unless otherwise noted, passing a null argument to a constructor or method in any class or interface

 * in this package will cause a {@link java.lang.NullPointerException NullPointerException} to be thrown.

 * The Javadoc "@param" definition is used to summarise the null-behavior.

 * The "@throws {@link java.lang.NullPointerException}" is not explicitly documented in each method.

 * </p>

 * <p>

 * All calculations should check for numeric overflow and throw either an {@link java.lang.ArithmeticException}

 * or a {@link java.time.DateTimeException}.

 * </p>

 * @since 1.8
