This is a great idea and a good Rails engine!

A minor, humble suggestion is to print the date including time-zone information in the html-only case (the component that's adjusted by javascript).

I.e. `November 27, 2013 11:43pm` could be written `November 27, 2013 11:43pm -06:00` or `2013-11-27T17:43Z`.

If js is off for some reason the time zone information is still there.
