# The page of the San Luis provincial government
# http://www.sanluis.gov.ar/notas.asp?idCanal=0&id=22812
# confirms what Alex Krivenyshev has earlier sent to the tz
# emailing list about that San Luis plans to return to standard
# time much earlier than the rest of the country. It also
# confirms that upon request the provinces San Juan and Mendoza
# refused to follow San Luis in this change.
#
! # The change is supposed to take place Monday the 21st at 0:00
# hours. As far as I understand it if this goes ahead, we need
# a new timezone for San Luis (although there are also documented
# independent changes in the southamerica file of San Luis in
# 1990 and 1991 which has not been confirmed).
! # From Jesper Nørgaard Welen (2008-01-25):
# Unfortunately the below page has become defunct, about the San Luis
# time change. Perhaps because it now is part of a group of pages "Most
# important pages of 2008."
#
# You can use
# http://www.sanluis.gov.ar/notas.asp?idCanal=8141&id=22834
# instead it seems. Or use "Buscador" from the main page of the San Luis
# government, and fill in "huso" and click OK, and you will get 3 pages
# from which the first one is identical to the above.
