477# From Paul Eggert (2013-09-05):
478# Perhaps San Luis operates on the legal fiction that it is at UTC-4
479# with perpetual summer time, but ordinary usage typically seems to
480# just say it's at UTC-3; see, for example,
481# <http://es.wikipedia.org/wiki/Hora_oficial_argentina>.
482# We've documented similar situations as being plain changes to
483# standard time, so let's do that here too. This does not change UTC
484# offsets, only tm_isdst and the time zone abbreviations. One minor
485# plus is that this silences a zic complaint that there's no POSIX TZ
486# setting for time stamps past 2038.
