Support for time-zones and their rules.
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.
Package specification
Unless otherwise noted, passing a null argument to a constructor or method in any class or interface
in this package will cause a NullPointerException to be thrown.
The Javadoc "@param" definition is used to summarise the null-behavior.
The "@throws NullPointerException" is not explicitly documented in each method.
All calculations should check for numeric overflow and throw either an ArithmeticException
or a DateTimeException.
