Flask-Moment not displaying anything on template

Found the answer to my question:

The template that needs to use Flask-Moment needs to contain the following lines:

{{ moment.include_jquery() }}
{{ moment.include_moment() }}

This wasn't in the book, yet I found the reference in the The Flask Mega-Tutorial, by the same author:

The times are not displayed as the is style='display: none;' in the tag. This will tell the browser to not display the tag. I don't know where it's comming from, but you should change it to style='display: inline;'.
