Apparently Fiji just changed their DST and end dates, 1 month before the predicted date (I say "apparently" because I can't find the order officially announced anywhere).

I feel like there's a good chance that there will be a lot of inconsistent clocks between November 7th and December 20th, and on January 16th, considering how long it takes for tzdata to propagate to all systems.
