| The pattern also applies to the previous end of DST in April 2012.
Actually, it applies to every instance of Summer Time (that we know
about) for Western Samoa, they've always selected the Last Sun in Sep
tp the first in April (no deviations at all) - they appear to just
be resisting committing to that for the future (even as much as
any political decision about the future is ever a real committment).
(Of course, "always" means "since Sep 2010" so this isn't quite as
compelling as it sounds...)
It only looks confused in the rules because of the missing day near
the end of 2011 when they jumped the date line.
In any case, this is one where (even more than Fiji) I think the
best course is to assume the rule, then adjust later if things change.
ps: Here's an ammended patch correcting the "lastSun" case typo
(zic doesn't object...) as just reported by lord.buddha at gmail.com
I'm still applying the rule only for future years to keep the
diff smaller (and so I don't have to think as much!)
