# rules...San Luis is still using "Western ARgentina Time" and it got
# stuck on Summer daylight savings time even though the summer is over.
+# From Paul Eggert (2013-09-05):
+# Perhaps San Luis operates on the legal fiction that it is at UTC-4
+# with perpetual summer time, but ordinary usage typically seems to
+# just say it's at UTC-3; see, for example,
+# <http://es.wikipedia.org/wiki/Hora_oficial_argentina>.
+# We've documented similar situations as being plain changes to
+# standard time, so let's do that here too. This does not change UTC
+# offsets, only tm_isdst and the time zone abbreviations. One minor
+# plus is that this silences a zic complaint that there's no POSIX TZ
+# setting for time stamps past 2038.
