A new Date and Time API for JDK 8 is being defined by JSR-310. This project is a backport of the API to JDK 7.
Please note that this is NOT an implementation of JSR-310. Only JDK 8 can contain an implementation of the JSR. This project simply mirrors the API in a different package. It is intended for use in applications that want an easy migration from JDK 7 to JDK 8.
