Also, there’s three three-way time-offset junctions in Europe (at this time of year), but they all have ‘hard’ international borders. If the junctions were in the Schengen Area, then it’d be like Cameron Corner, but I don’t think you can legally walk freely between countries (and time zones) at these three points, without using an official point of entry (I might be wrong about that, though).
