New Date and Time API introduced in Java 8 (aka JSR-310) is a big step forward comparing to what were available before in the JVM standard library. Sad thing that Java Architecture for XML Binding (JAXB) by default do not speak the new types. This library aims to address the issue by providing a collection of type adapters to enable use of Java 8 Date and Time API types in JAXB bindings.
In serialization/deserialization logic the library follows the ISO 8601 standard formats wherever applicable.
The Javadoc is available here.
