It's High Time: A New Date and Time API for the Java Platform
TS-6578

For years, developers have been facing problems with java.util.Date and java.util.Calendar. Zero-index-based months; performance and thread-safety issues; unpredictability; the difficulty of specifying and changing DST rules; and the lack of representations for other top-level concepts, such as non-time-zone dates or times, durations, periods, and intervals, are just some of the complaints of the community since the day the Java Platform, Standard Edition (Java SE platform) was released.

JSR 310, the Date and Time API, was submitted early in 2007 and has evolved a lot since its inception, with a published early draft and an upcoming public draft. Built on the lessons learned from the first two APIs, it provides a more advanced and comprehensive model for date and time manipulation and is being considered for inclusion in Java SE release 7.

This session examines this new API and its main concepts and features and shows code for handling common problems that are hard to solve with the existing classes. It also explains how code that uses the platform classes can be migrated and what impact this JSR will have on several other APIs. Besides that, it presents the current open issues and what solutions are being considered for them.

By the end of this session, attendees will understand the need for the new API, how to use it, and how it influences their current and future projects.
