1101# From Paul Eggert (2015-04-03): 1102# Shanks & Pottenger says America/Santiago introduced standard time in 1103# 1890 and rounds its UTC offset to 70W40; guess that in practice this 1104# was the same offset as in 1916-1919. It also says Pacific/Easter 1105# standardized on 109W22 in 1890; assume this didn't change the clocks. 1106# 1107# Dates for America/Santiago from 1910 to 2004 are primarily from 1108# the following source, cited by Oscar van Vlijmen (2006-10-08): 1109# [1] Chile Law 1110# http://www.webexhibits.org/daylightsaving/chile.html 1111# This contains a copy of a this official table: 1112# Cambios en la hora oficial de Chile desde 1900 (retrieved 2008-03-30) 1113# http://web.archive.org/web/20080330200901/http://www.horaoficial.cl/cambio.htm 1114# [1] needs several corrections, though. 1115# 1116# The first set of corrections is from: 1117# [2] History of the Official Time of Chile 1118# http://www.horaoficial.cl/ing/horaof_ing.html (retrieved 2012-03-06). See: 1119# http://web.archive.org/web/20120306042032/http://www.horaoficial.cl/ing/horaof_ing.html 1120# This is an English translation of: 1121# Historia de la hora oficial de Chile (retrieved 2012-10-24).

Go with [2]. 1129# 1130# - [1] says SMT was -4:42:45, [2] says Chile's official time from 1131# 1916 to 1919 was -4:42:46.3, the meridian of Chile's National 1132# Astronomical Observatory (OAN), then located in what is now 1133# Quinta Normal in Santiago. Go with [2], rounding it to -4:42:46. 1134# 1135# - [1] says the 1918 transition was Sep 1, [2] says Sep 10 and cites 1136# Bolet��n N�� 22, Aviso N�� 129/1918 (1918-08-23). Go with [2]. 1137# 1138# - [1] does not give times for transitions; assume they occur 1139# at midnight mainland time, the current common practice. However, 1140# go with [2]'s specification of 23:00 for the 1947-05-21 transition. 1141# 1142# Another correction to [1] is from Jesper N��rgaard Welen, who 1143# wrote (2006-10-08), "I think that there are some obvious mistakes in 1144# the suggested link from Oscar van Vlijmen,... for instance entry 66 1145# says that GMT-4 ended 1990-09-12 while entry 67 only begins GMT-3 at 1146# 1990-09-15 (they should have been 1990-09-15 and 1990-09-16 1147# respectively), but anyhow it clears up some doubts too." 1148# 1149# Data for Pacific/Easter from 1910 through 1967 come from Shanks & 1150# Pottenger. After that, for lack of better info assume 1151# Pacific/Easter is always two hours behind America/Santiago; 1152# this is known to work for DST transitions starting in 2008 and 1153# may well be true for earlier transitions. 1154 |

1101# From Eduardo Krell (1995-10-19): 1102# The law says to switch to DST at midnight [24:00] on the second SATURDAY 1103# of October....
