That's not a magic word Wikipedia uses; I'd venture a guess they want functionality like this template I found on a cursory Google search, in which case, a template like that template may need to be created. I don't know if that'll fix the whole problem, but yeah. It can't do math if it's trying to call things that don't exist. When you copy over a template (which you really should do with proper attribution on-wiki per CC-BY-SA), you have to bring over everything the template depends on.

If you don't need/care about the date being in Japanese Standard Time, you can just remove the instances of "JST" in the CURRENTX stuff and then it'll be magic words that work properly.

(@Andrewds1021--Hello Project Wiki got that template from Wikipedia and modified it to use local templates instead of magic words. OP copied it over to their wiki.)
