I'm not sure how this is treated "by the book" (however, I know, at least
in my linux's libc it 'just works').
To make a long story short, by 2009 Argentina stopped using DST and all of
the country is at UTC-0300.
However, the San Luis Province call this "Western Argentina Daylight
Savings Time" because they consider that WART is at UTC-0400 and they "got
stuck" in WARST (at UTC-0300), whereas the rest of the country calls this
Argentina Time at UTC-0300.
Rereading the southamerica source, I also notice there is no 'Arg' rule
after 2009 but, since there are no invocation of any of these rules after
2008, I think it's just fine.
