# mistakenly relied on data from Shanks & Pottenger saying that Quebec

# From Paul Eggert (2015-04-03):
# Shanks & Pottenger says America/Santiago introduced standard time in
# 1890 and rounds its UTC offset to 70W40; guess that in practice this
# was the same offset as in 1916-1919. It also says Pacific/Easter
# standardized on 109W22 in 1890; assume this didn't change the clocks.
#
# Dates for America/Santiago from 1910 to 2004 are primarily from
# the following source, cited by Oscar van Vlijmen (2006-10-08):
# [1] Chile Law
# http://www.webexhibits.org/daylightsaving/chile.html
# This contains a copy of a this official table:

# http://web.archive.org/web/20080330200901/http://www.horaoficial.cl/cambio.htm
# [1] needs several corrections, though.
#
# The first set of corrections is from:
# [2] History of the Official Time of Chile
# http://www.horaoficial.cl/ing/horaof_ing.html (retrieved 2012-03-06). See:
# http://web.archive.org/web/20120306042032/http://www.horaoficial.cl/ing/horaof_ing.html

# A fancier Spanish version (requiring mouse-clicking) is at:
# http://www.horaoficial.cl/historia_hora.html
# Conflicts between [1] and [2] were resolved as follows:
#
# - [1] says the 1910 transition was Jan 1, [2] says Jan 10 and cites
# Boletín Nº 1, Aviso Nº 1 (1910). Go with [2].
#
# - [1] says SMT was -4:42:45, [2] says Chile's official time from
# 1916 to 1919 was -4:42:46.3, the meridian of Chile's National
# Astronomical Observatory (OAN), then located in what is now
# Quinta Normal in Santiago. Go with [2], rounding it to -4:42:46.
#
# - [1] says the 1918 transition was Sep 1, [2] says Sep 10 and cites
# Boletín Nº 22, Aviso Nº 129/1918 (1918-08-23). Go with [2].
#
# - [1] does not give times for transitions; assume they occur
# at midnight mainland time, the current common practice. However,
# go with [2]'s specification of 23:00 for the 1947-05-21 transition.
#
# Another correction to [1] is from Jesper Nørgaard Welen, who
# wrote (2006-10-08), "I think that there are some obvious mistakes in
# the suggested link from Oscar van Vlijmen,... for instance entry 66
# says that GMT-4 ended 1990-09-12 while entry 67 only begins GMT-3 at
# 1990-09-15 (they should have been 1990-09-15 and 1990-09-16
# respectively), but anyhow it clears up some doubts too."
#
# Data for Pacific/Easter from 1910 through 1967 come from Shanks &
# Pottenger. After that, for lack of better info assume
# Pacific/Easter is always two hours behind America/Santiago;
# this is known to work for DST transitions starting in 2008 and
