For those wanting to hit the ground running with the project, I’ve posted a video on what needs deploying to the server and your client, embedded below.
Declan has also updated the JavaDoc and is kindly hosting it.
For anyone who wants a bit more information on how to use the code and some comparisons, I’ve been working on a sample application. It requires M2 as a minimum. So far there is import code and some samples of some new methods in DateTime. There is also some code to performance benchmark. I would recommend downloading from GitHub (using Git rather than Mercurial) because I will be continuing to work on it. But if you’re not comfortable yet with source control, I’m attaching a copy of the database.
