Indeed, it's here: https://mklauber.github.io/tw5-plugins At the time, I was running into an issue where I couldn't use <<time "[UTC]YYYY0MM0DD0hh0mm0ssXXX">> as a param to a filter, so I couldn't make it deterministic and easily based on render time. I'm seeing some interesting ideas here though in Mario's post to create some default seed tiddlers to update. If there's interest in trying to get this into the core, I'd be happy to work on it. As it is, my plugin, non-deterministic as it is, hasn't been an issue in my years of using it.
