I believe you are mistaken. Is this the page you were looking at? That is indeed a Lua module but it is used instead of EasyTimeline. It is not EasyTimeline. EasyTimeline is a MediaWiki extension that should already be enabled on your wiki. The page I linked to in my previous post should have a description on how to use it.
