# ...the Province of San Luis is a case in itself.

# The Law at

# is that "The province will most likely follow the next daylight saving schedule,
# which is planned for the second Sunday in October."
# is ambiguous because establishes a calendar from the 2nd Sunday in
# October at 0:00 thru the 2nd Saturday in March at 24:00 and the
# complement of that starting on the 2nd Sunday of March at 0:00 and
# ending on the 2nd Saturday of March at 24:00.
#
# This clearly breaks every time the 1st of March or October is a Sunday.
#
# IMHO, the "spirit of the Law" is to make the changes at 0:00 on the 2nd
# Sunday of October and March.
#
# The problem is that the changes in the rest of the Provinces that did
# change in 2007/2008, were made according to the Federal Law and Decrees
# that did so on the 3rd Sunday of October and March.
#
# In fact, San Luis actually switched from UTC-4 to UTC-3 last Sunday
# (October 11th) at 0:00.
#
# So I guess a new set of rules, besides "Arg", must be made and the last
# America/Argentina/San_Luis entries should change to use these...
#
# I'm enclosing a patch that does what I say... regretfully, the San Luis
# timezone must be called "WART/WARST" even when most of the time (like,
# right now) WARST == ART... that is, since last Sunday, all the country
# is using UTC-3, but in my patch, San Luis calls it "WARST" and the rest
# of the country calls it "ART".
