| 707# From Gwillim Law (2001-05-04): 708# I came across another article in "La Tercera" about Chilean DST. 709# <http://www.tercera.cl/diario/2000/10/13/t-extras.html> 710# It clearly confirms my earlier suggestion, that DST begins at 22:00 711# on Easter Island.... But it also seems to be saying that the 712# observance of DST in Chile began in 1966, rather than 1969 as 713# ... [Shanks & Pottenger have] it.... 714# 715# My translation: 716# 717# "The Chilean Army has announced that summer time will begin tomorrow, 718# Saturday, October 14 in continental Chile, insular Chile, and 719# Antarctica, as provided by Supreme Decree 25 of January 11, 1966. 720# By the preceding, official time in continental Chile and Chilean 721# Antarctic, and official time in Western Insular Chile, which applies 722# to Easter Island and Sala y Gomez Island, will be set forward at 723# midnight and at 22:00, respectively, by 20 minutes." | 707# From Oscar van Vlijmen (2006-10-08): 708# http://www.horaoficial.cl/cambio.htm |
| 724 | 709 |
| 725# From Paul Eggert (2006-03-22): 726# Go with Law in preference to Shanks & Pottenger's 1969 date for modern DST. 727# Assume this rule has been used since DST was introduced in the islands. | 710# From Jesper Norgaard Welen (2006-10-08): 711# I think that there are some obvious mistakes in the suggested link 712# from Oscar van Vlijmen,... for instance entry 66 says that GMT-4 713# ended 1990-09-12 while entry 67 only begins GMT-3 at 1990-09-15 714# (they should have been 1990-09-15 and 1990-09-16 respectively), but 715# anyhow it clears up some doubts too. |

| 729# From Paul Eggert (2002-10-24): 730# <http://www.shoa.cl/shoa/faqhoraoficial.htm> gives many details that 731# disagree with the following table, but we haven't had time to compare them. | 717# From Paul Eggert (2006-12-27): 718# The following data for Chile and America/Santiago are from 719# <http://www.horaoficial.cl/horaof.htm> (2006-09-20), transcribed by 720# Jesper Norgaard Welen. The data for Pacific/Easter are from Shanks 721# & Pottenger, except with DST transitions after 1932 cloned from 722# America/Santiago. The pre-1980 Pacific/Easter data are dubious, 723# but we have no other source. |
