For those that simply repeat or skip a whole calendar day, life is
fairly simple. However, Alaska's 24-hour transition at 15:30 LMT Sitka
(incidentally combined with a change of calendar) is a bit trickier.
Also fix a typo I noticed in passing.
Write tests to determine what the actual behavior is and document
enough to make the actual behavior seem unsurprising once encountered,
without trying to go into all the excruciating details. Naturally, MS
time-zone data lacks the data on the historic transitions involved in
these tests, so MS (when not using ICU's time-zone data) is excluded.
It seems Cupertino believes Alaska was always in the USA, too.
