rare example of a published article stating the DLS opposition viewpoint
(the scarcity of which is by no means an accident!). Full of sound scientific
arguments and social obvervations concerning the misguided push to introduce
daylight saving to Queensland. The article originally appeared at the
political website Online
Opinion, where it includes comments from readers. 'Daylight
saving energy?', Andrew Bartlett, 16 January 2007
by Andrew Bartlett, Australian Senator and Brisbane resident, who mainly
argues against daylight saving for Queensland, and in favour of more research
on the viability of the energy saving argument.
Brisbane-based blog that comes out against daylight saving. Good article
- and also interesting to view the blog comments at the end, which are
almost entirely split along temperate/tropical lines.
lively dissection of the main arguments put forward by Queensland's pro
daylight saving business lobby each year in the media.
put the above article in perspective, anyone who is interested in the
reality of Queensland's business and economic health - as opposed to the
'financial backwater' and 'commercial hardship' mythology heavily promoted
by the Brisbane-Gold Coast pro-daylight saving lobby - could take a look
at this article at the Australian
Bureau of Statistics. In all categories of economic criteria, Australia's
two standard time states - Queensland and Western Australia - rank either
at the top or above the national average.
Western Australia daylight saving trial, May 2009
On 16 May
2009, West Australians went to the polls to vote in their fourth daylight
saving referendum in just over 30 years. The referendum was defeated in
WA's biggest ever No vote. Here is a collection of the main No-friendly
articles that featured in the media in the lead-up to the referendum.
on overall empirical data from Indiana during the first two years after
it switched to daylight saving in 2004, University of California (Santa
Barbara) researchers Matthew Kotchen and Laura Grant have found that the
Indiana clock change has led to an increase of 1% annually (and up to
4% in the fall) - translating to an increase of $9 million to the state
in energy costs. Added to this is the social cost of an estimated pollution
increase of up to $5.5 million per year.
paper from the California Energy Commission, which concludes that
the recently implemented US (2007) daylight savings extension is likely
to merely shift electricity use to off-peak hours rather than create a
significant drop in power usage. Electricity use could decline 0.5 percent,
'but the savings could just as well be zero.’ [Highly
Does Extending Daylight Saving Save Energy? Evidence from an Australian
Experiment, Centre for the Study of Energy Markets (CSEM), University
of California, January 2007
This study from the University of California, based on data from the early
(winter) shift to daylight saving in Victoria, Australia prior to the
2000 Sydney Olympics, actually reports a negative energy
saving. The report concluded that reduced
energy use in the evening hours was entirely negated by the new morning
spike in power consumption as Victorian households turned on their lights
and heaters while getting ready for work.’

of daylight saving as a way of reducing the demand on baseload energy

entry for a US health and fitness site that carries a poll and commentary
section. At time of writing, the poll results in answer to the question
'Is daylight saving adversely affecting you?' are 77% (175 votes) Yes,
and 23% No (53 votes). Although online polls are far from representative
samples, the fact that this is a health and fitness blog and that it seems
to be targeting young women indicate that acceptance of daylight saving
could well be waning over time.

'This darker side of daylight-saving time
has some doctors and researchers concerned about the impact the earlier
time change [since the US 2007 DST extension)will have on people with
winter depression. That's because there is a growing body of research
showing that dark mornings—not short days—are the real trigger
for seasonal affective disorder, a form of clinical depression that occurs
cyclically every winter.'
from two German studies, using a large (n = 55,000) and small population
sample (n = 50), both of which reveal that people readily adjust to the
release from DST in autumn but poorly adjust to the DST imposition in
spring - largely because humans adjust to the east-west
progression of dawn within a given time zone. The studies conclude that
the disruptive effects of DST are 'poorly understood' and that 'this disruption
may extend to other aspects of seasonal biology in humans'. *'Daylight

from an interview with sleep expert Dr. Michael Breus on sleep disorders
and the affects of daylight saving time.
German and Dutch researchers looked
at 55,000 people in Central Europe and concluded that the human circadian
system (the body’ day-night cycle) does not adjust to daylight saving
time. A separate part of the researchers’ work looked at 50 subjects
and found that both early birds and night owls handled the end of daylight
saving in fall better than the start in spring.

This article presents the findings of a Canadian team of economists who
examined market returns 1967 to 1997 across four countries - Canada, the
US, the UK and Germany. They found an average larger negative return than
the mean regular weekend for every index they looked at - in fact, the
negative difference was 2 to 5 times greater than the average fluctuations
on normal weekends. Translated into monetary terms, and in the US context
alone, the 'daylight saving effect' implies a one-day average loss of
$31 billion dollars.

highly readable book by American writer/novelist Michael Downing meticulously
charts the century-long history of daylight saving as the stubborn growth

masked as piety, and mysteriously shifting time-zone boundaries ... a
true-to-life social comedy'.
any myths that daylight saving was ever about the lifestyle wishes of
ordinary people. The long arm of big business, big media and big government

savings time (DST) is probably one of the most annoying inventions of
the human race. Each year people spend a week or so adjusting to an hour
forwards or backwards causing all sorts of erratic behavior and poor sleep
while people adjust. Last year the U.S. Government decided to take it
a step further and cause IT professionals and IT vendors to spend plenty
of time and money to satisfy a few politicians with a not so brilliant
of an article, describing the very under-reported IT headaches caused
by daylight saving - in the context of the latest US extension. No doubt,
a similar set of headaches is occurring now in Australia as a result of
its latest DS extension, but will no doubt be 'absorbed' into a general
consensus of how much better off we all are for having it.
Swatch Internet Time was a decimal time concept introduced in 1998 and
marketed by the Swatch corporation as an alternative, decimal measure

Union Law Summertime Directive shows the full text of the
European Daylight Saving legislation, as at March 2002. Article 2 of thedirective
states that the choice to join daylight saving is up to the individual
member states and only the annual start/end dates are the EU's concern:
that the Member States apply summer-time arrangements, it is important
for the functioning of the internal market that a common date and time
for the beginning and end of the summer-time period be fixed throughout
However, this right of 'choice' is applied quite differently in practice.
In 1996, the French government attempted to opt out of Summertime but
backed down after it was threatened by the EU with legal action. This
issue is also covered in Light
