Parsing and formatting time

[marjan-georgiev]

The parseDate and formatDate functions don't seem to support any time formats: http://jsfiddle.net/BvC5j/2/

We are using moment.js in a project, and I was able to fix this by changing the functions to use moment's parsing/formatting methods. I can submit a pull request, but that would require having moment.js as a dependency. Please let me know.
