Hi, with respect to 2012c south america. San Luis appears to have a zone/rule inconsistency. The latest zone indicates using rule SanLuis, but the rule is used only until 2009. For dates past 2009 is there consistency?

Well...
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. -- Mariano Absatz - El Baby www.clueless.com.ar
