Date Tools Plugin

I’ve created a datetools plugin that will be useful as soon as 0.9.13 is rolled out. It provides various common dates to be used in twig templates.

I’ll be adding more methods and documentation in the next 24-48 hours.

Ok, i’m going to finish up the new feature I was working on and get 0.9.13 out!
