32 # From Paul Eggert (2006-03-22):
33 # A good source for time zone historical data outside the U.S. is
34 # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
35 # San Diego: ACS Publications, Inc. (2003).
36 #
37 # Gwillim Law writes that a good source
38 # for recent time zone data is the International Air Transport
39 # Association's Standard Schedules Information Manual (IATA SSIM),
40 # published semiannually. Law sent in several helpful summaries
41 # of the IATA's data after 1990.
42 #
43 # Except where otherwise noted, Shanks & Pottenger is the source for
44 # entries through 1990, and IATA SSIM is the source for entries afterwards.
45 #
46 # Earlier editions of these tables used the North American style (e.g. ARST and
47 # ARDT for Argentine Standard and Daylight Time), but the following quote
48 # suggests that it's better to use European style (e.g. ART and ARST).
49 # I suggest the use of _Summer time_ instead of the more cumbersome
50 # _daylight-saving time_. _Summer time_ seems to be in general use
51 # in Europe and South America.
52 # -- E O Cutler, _New York Times_ (1937-02-14), quoted in
53 # H L Mencken, _The American Language: Supplement I_ (1960), p 466
54 #
55 # Earlier editions of these tables also used the North American style
56 # for time zones in Brazil, but this was incorrect, as Brazilians say
387 # America/Cordoba split into 6 subregions during 1991/1992, one of which
388 # was America/San_Luis, but we haven't verified this yet so for now we'll
389 # keep America/Cordoba a single region rather than splitting it into the
390 # other 5 subregions.
391
392 # From Mariano Absatz (2009-03-13):
393 # Yesterday (with our usual 2-day notice) the Province of San Luis
394 # decided that next Sunday instead of "staying" @utc-03:00 they will go

1257 # The Chilean Government has decided to postpone the entrance into winter time

1260 # Quote from the website communication:
1261 #
1262 # 6. For the year 2012, the dates of entry into winter time will be as follows:
1263 # a. Saturday April 28, 2012, clocks should go back 60 minutes; that is, at
1264 # 23:59:59, instead of passing to 0:00, the time should be adjusted to be 23:00

1266 # b. Saturday, September 1, 2012, clocks should go forward 60 minutes; that is,

32 # From Paul Eggert (2006-03-22):
33 # A good source for time zone historical data outside the U.S. is
34 # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
35 # San Diego: ACS Publications, Inc. (2003).
36 #
37 # For data circa 1899, a common source is:
38 # Milne J. Civil time. Geogr J. 1899 Feb;13(2):173-94
39 # <http://www.jstor.org/stable/1774359>.
40 #
41 # Gwillim Law writes that a good source
42 # for recent time zone data is the International Air Transport
43 # Association's Standard Schedules Information Manual (IATA SSIM),
44 # published semiannually. Law sent in several helpful summaries
45 # of the IATA's data after 1990.
46 #
47 # Except where otherwise noted, Shanks & Pottenger is the source for
48 # entries through 1990, and IATA SSIM is the source for entries afterwards.
49 #
50 # Earlier editions of these tables used the North American style (e.g. ARST and
51 # ARDT for Argentine Standard and Daylight Time), but the following quote
52 # suggests that it's better to use European style (e.g. ART and ARST).
53 # I suggest the use of _Summer time_ instead of the more cumbersome
54 # _daylight-saving time_. _Summer time_ seems to be in general use
55 # in Europe and South America.
56 # -- E O Cutler, _New York Times_ (1937-02-14), quoted in
57 # H L Mencken, _The American Language: Supplement I_ (1960), p 466
58 #
59 # Earlier editions of these tables also used the North American style
60 # for time zones in Brazil, but this was incorrect, as Brazilians say
391 # America/Cordoba split into 6 subregions during 1991/1992, one of which
392 # was America/San_Luis, but we haven't verified this yet so for now we'll
393 # keep America/Cordoba a single region rather than splitting it into the
394 # other 5 subregions.
395
396 # From Mariano Absatz (2009-03-13):
397 # Yesterday (with our usual 2-day notice) the Province of San Luis
398 # decided that next Sunday instead of "staying" @utc-03:00 they will go
399 # to utc-04:00 until the second Saturday in October...

415 # ... announced that next Sunday, at 00:00, Puntanos (the San Luis
416 # inhabitants) will have to turn back one hour their clocks
417 #
418 # Since then, San Luis will establish its own Province timezone. Thus,
419 # during 2009, this timezone change will run from 00:00 the third Sunday
420 # in March until 24:00 of the second Saturday in October.
