# Queensland
#
# From Alex Livingston (1996-11-01):
# I have heard or read more than once that some resort islands off the coast
# of Queensland chose to keep observing daylight-saving time even after
# Queensland ceased to.
#
# From Paul Eggert (1996-11-22):
# IATA SSIM (1993-02/1994-09) say that the Holiday Islands (Hayman, Lindeman,
# Hamilton) observed DST for two years after the rest of Queensland stopped.
# Hamilton is the largest, but there is also a Hamilton in Victoria,
# so use Lindeman.
#
# From J William Piggott (2016-02-20):
# There is no location named Holiday Islands in Queensland Australia; holiday
# islands is a colloquial term used globally. Hayman and Lindeman are at the
# north and south extremes of the Whitsunday Islands archipelago, and
# Hamilton is in between; it is reasonable to believe that this time zone
# applies to all of the Whitsundays.

# For now, guess DST from 02:00 the second Sunday in November to 03:00

# In a 2021-10-10 speech concerning updated Covid-19 mitigation measures in
# Fiji, prime minister Josaia Voreqe "Frank" Bainimarama announced the
# suspension of DST for the 2021/2022 season: "Given that we are in the process
# of readjusting in the midst of so many changes, we will also put Daylight
# Savings Time on hold for this year. It will also make the reopening of
# scheduled commercial air service much smoother if we don't have to be
# concerned shifting arrival and departure times, which may look like a simple
# thing but requires some significant logistical adjustments domestically and
# internationally."
# From Shalvin Narayan (2022-10-27):
# Please note that there will not be any daylight savings time change
# in Fiji for 2022-2023....

#
# From Michael Deckers (2021-03-24):
# ... in the Cook Island Act of 1915-10-11, online at
# http://www.paclii.org/ck/legis/ck-nz_act/cia1915132/
# "651. The hour of the day shall in each of the islands included in the
# Cook Islands be determined in accordance with the meridian of that island."
# so that local (mean?) time was still used in Rarotonga (and Niue) in 1915.
# This was changed in the Cook Island Amendment Act of 1952-10-16 ...
# http://www.paclii.org/ck/legis/ck-nz_act/ciaa1952212/
# "651 (1) The hour of the day in each of the islands included in the Cook
# Islands, other than Niue, shall be determined as if each island were
# situated on the meridian one hundred and fifty-seven degrees thirty minutes
# West of Greenwich. (2) The hour of the day in the Island of Niue shall be
# determined as if that island were situated on the meridian one hundred and
# seventy degrees West of Greenwich."
# This act does not state when it takes effect, so one has to assume it
# applies since 1952-10-16. But there is the possibility that the act just
# legalized prior existing practice, as we had seen with the Guernsey law of
# 1913-06-18 for the switch in 1909-04-19.

# Inhabited by civilians 1935-1942; U.S. military bases 1943-1944;

# Howland observed Hawaii Standard Time (UT -10:30) in 1937;
# see page 206 of Elgen M. Long and Marie K. Long,

# Johnston
#
# From Paul Eggert (2017-02-10):
# Sometimes Johnston kept Hawaii time, and sometimes it was an hour behind.
# Details are uncertain. We have no data for Johnston after 1970, so
# treat it like Hawaii for now. Since Johnston is now uninhabited,
# its link to Pacific/Honolulu is in the 'backward' file.
#
# In his memoirs of June 6th to October 4, 1945
# <http://www.315bw.org/Herb_Bach.htm> (2005), Herbert C. Bach writes,
# "We started our letdown to Kwajalein Atoll and landed there at 5:00 AM
# Johnston time, 1:30 AM Kwajalein time." This was in June 1945, and
# confirms that Johnston kept the same time as Honolulu in summer 1945.
#
# From Lyle McElhaney (2014-03-11):
# [W]hen JI was being used for that [atomic bomb] testing, the time being used
# was not Hawaiian time but rather the same time being used on the ships,
# which had a GMT offset of -11 hours. This apparently applied to at least the
# time from Operation Newsreel (Hardtack I/Teak shot, 1958-08-01) to the last
# Operation Fishbowl shot (Tightrope, 1962-11-04).... [See] Herman Hoerlin,

# Impact on the Environment", Los Alamos LA-6405, Oct 1976.
# https://www.fas.org/sgp/othergov/doe/lanl/docs1/00322994.pdf
