  34 # Unless otherwise specified, the source for data through 1990 is:
  35 # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
  36 # San Diego: ACS Publications, Inc. (2003).
  37 # Unfortunately this book contains many errors and cites no sources.
  38 #
  39 # Many years ago Gwillim Law wrote that a good source
  40 # for time zone data was the International Air Transport
  41 # Association's Standard Schedules Information Manual (IATA SSIM),
  42 # published semiannually.  Law sent in several helpful summaries
  43 # of the IATA's data after 1990.  Except where otherwise noted,

 402 
 403 # From Mariano Absatz (2010-04-12):
 404 # yes...I can confirm this...and given that San Luis keeps calling
 405 # UTC-03:00 "summer time", we should't just let San Luis go back to "Arg"
 406 # rules...San Luis is still using "Western ARgentina Time" and it got
 407 # stuck on Summer daylight savings time even though the summer is over.
 408 
 409 # From Paul Eggert (2018-01-23):
 410 # Perhaps San Luis operates on the legal fiction that it is at -04
 411 # with perpetual daylight saving time, but ordinary usage typically seems to
 412 # just say it's at -03; see, for example,
 413 # https://es.wikipedia.org/wiki/Hora_oficial_argentina
 414 # We've documented similar situations as being plain changes to
 415 # standard time, so let's do that here too.  This does not change UTC
 416 # offsets, only tm_isdst and the time zone abbreviations.  One minor
 417 # plus is that this silences a zic complaint that there's no POSIX TZ
 418 # setting for time stamps past 2038.

 405 # From Mariano Absatz (2010-04-12):
 406 # yes...I can confirm this...and given that San Luis keeps calling
 407 # UTC-03:00 "summer time", we should't just let San Luis go back to "Arg"
 408 # rules...San Luis is still using "Western ARgentina Time" and it got
 409 # stuck on Summer daylight savings time even though the summer is over.
 410 
 411 # From Paul Eggert (2018-01-23):
 412 # Perhaps San Luis operates on the legal fiction that it is at -04
 413 # with perpetual daylight saving time, but ordinary usage typically seems to
 414 # just say it's at -03; see, for example,
 415 # https://es.wikipedia.org/wiki/Hora_oficial_argentina
 416 # We've documented similar situations as being plain changes to
 417 # standard time, so let's do that here too.  This does not change UTC
 418 # offsets, only tm_isdst and the time zone abbreviations.  One minor
 419 # plus is that this silences a zic complaint that there's no POSIX TZ
 420 # setting for timestamps past 2038.
