## Package java.time.zone Description

### 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`.

Since:
  JDK1.8
