EVALUATION

Tzdata changes for Argentina and others. are under review by the tz mailing list. Those changes will be supported when the new tzdata release is available.

According to http://www.lanacion.com.ar/politica/nota.asp?nota_id=973996 , DST starts from 2007-12-30T00:00:00 (local standard time), not 2008-01-01T00:00:00.
