| 454# From Paul Eggert (2013-09-05): 455# Perhaps San Luis operates on the legal fiction that it is at UTC-4 456# with perpetual summer time, but ordinary usage typically seems to 457# just say it's at UTC-3; see, for example, 458# <http://es.wikipedia.org/wiki/Hora_oficial_argentina>. 459# We've documented similar situations as being plain changes to 460# standard time, so let's do that here too. This does not change UTC 461# offsets, only tm_isdst and the time zone abbreviations. One minor 462# plus is that this silences a zic complaint that there's no POSIX TZ 463# setting for time stamps past 2038. 464 |
