I don't know how much the wiki code is just taken from elsewhere, though it does use the same rich text editor so I assume jase has at least tweaked it.
The quirk is that the dates in the Version screen for a page are in the single worst format I can imagine: YYYY/DD/MM
Really? No one in the world uses that format, and it makes no sense. Americans will fight with Europeans whether DD/MM/YYYY or MM/DD/YYYY is better, so it's a smart move to change to a year-first approach, with the idea that you go from most to least significant. But don't then put the days before the month.
