Thanks. The wording in that English translation is a bit ambiguous, but it does appear that it's more likely that the change is permanent than that it's a one-year thing. So here's a proposed tz patch to implement this, which I've pushed to the experimental repository on github. This isn't urgent, since we already have this year's transitions right; the first affected timestamp is in March 2014.
