sys-libs/timezone-data-2008 DST change for Argentina. Wrong time zone from Oct 5. (GMT -2) Argentinian law N° 25.155 is no longer valid. http://www.infoleg.gov.ar/infolegInternet/anexos/60000-64999/60036/norma.htm The new one is law N° 26.350 http://www.infoleg.gov.ar/infolegInternet/anexos/135000-139999/136191/norma.htm So there is no summer time in Argentina for now. See this bug in Debian https://bugs.launchpad.net/debian/+source/tzdata/+bug/278419 I don't know where to inform this to update tzdata & tzcode Thanks
the place to report these things is: tz@elsie.nci.nih.gov
