>Description:
The Argentine Congress approved a law to change the current timezone to observe DST. I couldn't find any FreeBSD-specific information about this change so I decided to submit this as a PR.

The timezone change will take place on the 30th of December 2007 at 00:00, moving the clock forward to 01:00 and it will return to normal on the 16th of March 2007 at 00:00.

That means from December 30th to March 16th we will be at GMT-2 and then
back to GMT-3.

The official bulletin is available at http://www.boletinoficial.gov.ar/bora.portal/PrimeraSecci%C3%B3n/tabid/53/Default.aspx

The specific law for the time change is 26.350.

Unfortunately the change was very abrupt with very little notice given and since it's already in effect there's probably a high number of affected systems in the wild right now.
