if you wait long enough, the multi-minute jump that you then need isn't a "leap" anything, it's a political change to the definition of a time zone, readily handled by the well-tried mechanism that we on this list all know and love.
This should be fun once we start changing time zones to to be more than 24 hours away from where they are now.
Everyone on this list will be safely dead before any of that matters, but ... how would that work really? I think most people understand time zones as "offsets from UTC". We know how to cope with changes in those offsets, having done it many times before. But it's not clear to me how tzdb could handle step changes in UTC itself in the same way. That looks morally equivalent to leap seconds, which is exactly the under-tested case we're bemoaning in this thread. regards, tom lane
