ThreeTen-Extra provides additional date-time classes that complement those in Java SE 8.
Not every piece of date/time logic is destined for the JDK. Some concepts are too specialized or too bulky to make it in. This project provides some of those additional classes as a well-tested and reliable jar. It is curated by the primary author of the Java 8 date and time library, Stephen Colebourne.
