Well maybe, although some of this might be treated a bit differently. I
guess I'll have to look those examples up, but a "1 time per year" sounds
more like a permanent shift in base time from UTC then dst change.  And not
sure what you'd do with 3 either.  If that's the case, v2 will have to
treat these events as a list.
