There is a paragraph that asserts a history of changes to the Argentina time zone offset between 1920 and 1993. The most reliable (though not authoritative) source I have access to is the tz database (a.k.a. Olsen database) which attempts to be a comprehensive database of all current and historical timezones from at least 1970 to the present, with less comprehensive, but still volumnious information about pre-1970 time zones. The time zone changes asserted in the article do not correspond to the time zone changes documented in the tz database. It is possible that this is due to incomplete information in the tz database, since it does not claim to actually have achieved comprehensive coverage of historical time zone changes.
Can anyone find any other source to document the asserted time zone history? Scott Roy Atwood ( talk) 01:17, 9 October 2009 (UTC)
there is nothing 'unofficial' about Argentina not observing daylight savings in 2009. I live there and I can assure you that there is no DST this year. —Preceding unsigned comment added by 190.247.227.30 ( talk) 01:57, 26 October 2009 (UTC)
At least in one instance (I think it was the same 2009 event alluded to earlier), a last-minute political decision to postpone daylight savings time led to an emergency bug in Ubuntu's Launchpad. The comments on the bug seem to imply that this happens frequently. Is this a widespread phenomenon with other pieces of software? Perhaps the article should mention this? -- 75.28.98.179 ( talk) 05:42, 12 June 2013 (UTC)
