If you want to contribute to the project (perhaps fix a bug, or reflect a change in time zone rules), please simply issue a Pull Request. Don't worry about [Grunt] builds etc, all you need to modify is the jstz.js file and I'll take care of the testing/minifying etc.
+* [Josh Fraser] for the original idea
+* [Brian Donovan] for making jstz CommonJS compliant
+* [Ilya Sedlovsky] for help with namespacing
