proposed tzdata fixes for Brazil, Argentina, Israel
Since the tz database is incorrect for some current time stamps in Argentina and Brazil, it's time for another update. Here's a proposed patch to implement the following changes: * Brazil has changed the DST start-date due to problems with its election software, and Mato Grosso will observe DST this year. (Thanks to Paulo Alexandre Pinto Pires and Rodrigo Severo for this info.) * Mendoza, Argentina is now back at -0300 (effective Sept 26). (Thanks to Steffen Thorsen for this info.) * San Juan, Argentina changed back to -0300 on July 25, and its transition date to -0400 was May 31, not June 1. (Thanks to Mariano Absatz for this info.) The following change affects commentary only: * Israel's Cabinet has discussed new DST rules but no decision has been reached yet.
