DST thread disappeared

Orion402

A relevant comment on DST and why clocks go forward rather than backwards when the hour hand goes back one hour in October and it is removed from this forum. The meteorologists will remind viewers of the need to put their clocks back in October despite the technical details which determine what DST does. Leave the explanation for what it is without further comment or moderation as it is new to most observers and no accurate explanation exists out there

The effect of putting the clock hand back one hour is to return the clock forward to natural noon and its normal anchor in the sunrise/noon/sunset cycle. There is a normal symmetry between sunrise and noon on one side and noon to sunset on the other before DST is applied. By moving the clock hand forward by one hour in Spring, the length of time between clock noon and sunset increases by an hour hence 'longer evenings' while the length of time from sunrise to clock noon decreases by one hour.

Whoever removed the privilege of using links to demonstrate what happens is petty and does Irish society no favours, however, the discussion brings back the connection between one rotation and one sunrise/noon/sunset cycle linked to timekeeping. People should be ashamed of themselves until they accept accurate explanations that are presently not in existence and actively removed because it does not suit those who would keep people ignorant.

I'm unsure as to what point you're trying to make? Are you just having an online waffle? Are you trying to start a discussion?

Orion402

Tomorrow the Met Eireann forecaster will announce the arrival of meteorological Autumn despite the fact that the annual cycle is anchored to midsummer on the June Solstice just as daily rotation is anchored to the sunrise/noon/sunset cycle. There is no astronomical noon versus meteorological noon as temperatures rise after 12 PM (post meridiem) and likewise the annual cycle is anchored from March Equinox (sunrise) to the September Equinox (sunset) with the June Solstice acting as annual noon. This is no trivial discussion on whether Autumn begins at the start of August, this is the relationship between planetary motions and temperatures along with effects (hurricane season, Arctic ice season, ect) which constitute both geographical and planetary climate as distinct yet intertwined.

The disgraceful attempt to disappear the previous thread on the DST explanation (albeit locked) reflects poorly on contributors here and all the bag of tricks like 'what's the point', 'what has this to do with weather? ', prohibiting graphics and explanations just goes to demonstrate how those petty people do mind.

Clocks go forward to their normal correlation between natural noon and 24 hour clock noon on the October adjustment even as the clock hand goes back. This is for observers who can develop an understanding of the relationship between timekeeping and the daily cycle, including temperature fluctuations, while using the explanation as a point for departure for explaining the annual hemispherical fluctuation as a function of the orbital motion of the Earth and a separate rotation to the Sun parallel to the orbital plane.

Once the annual temperature fluctuation is explained then it moves on to planetary climate and the rate of change in atmospheric and surface conditions as a function of the relationship between rotational inclination and the orbital plane.

If you hadn't registered so many time then you'd be able to post links, etc.

Everyone knows that temperatures rise after midday. Everyone knows that temperatures rise after the June Solstice. What's DST got to do with anything?

Meteorological summer, just like the other seasons, is based on average monthly temperatures, which peak in July. That's it. There's no conspiracy.

Orion402

The way DST works off an asymmetry between natural sunrise and clock noon along with the extra hour between clock noon and natural sunset, thereby giving 'longer evenings' by moving the clock backwards in Spring through the natural cycle is a gorgeous topic that seques off into the wider topics of meteorology, climate, timekeeping, Earth sciences, solar system and Universal research. Clocks go forward at the end of October and while it may cause some people to pause, the reasons why are as satisfying as all the others for those who can be inspired no matter who tries to meddle with the explanation by their crude antics.

Maybe people can justify their silence as much as they can the silly reactions to an explanation that extends the human productivity and creativity in the right direction but there is nothing trivial about this topic and would be for those who are not petty and small.

The foundations of timekeeping begin with the calendar framework and many thousands of years later involved the creation of clocks with their equable hours, minutes and seconds tied to the sunrise/noon/sunset cycle. The DST adjustment is an outrigger of this framework where clock noon moves back one hour towards sunrise as the hour hand moves forward one hour in the Spring.

The late 17th century empiricists and their clockwork solar system decided to shift the reference for each rotation away from the sunrise/noon/sunset cycle and towards the daily change in position of the stars in circumpolar motion around Polaris by misusing a clock and the calendar framework. They attempted to make timekeeping linear and created a fictional narrative of 'solar time versus sidereal time' to justify their vandalism. Recently, they have invented the 'astronomical seasons versus the meteorological seasons' in much the same type of vandalism that serves nobody and worse, distracts from the seasonal explanation which uses the Equinoxes and June Solstice as annual markers for the great surface rotation as a function of the orbital motion of the Earth where the entire surface of the planet turns parallel to the orbital plane once each year.

The fact that clocks move forward when DST is removed is no anecdotal narrative, but rather a technical issue that ties into many other technical issues. It takes genuine researchers to know what is being said.

I make huge allowances for those people who are unable to appreciate what is being said including the fact that clocks move forward at the end of October rather than back as proposed by everyone from RTE to the European Parliament-

" MEPs have voted to scrap the practice of moving clocks forward by an hour in Spring then back again in the autumn in the EU from April 2021, two years later than the EU executive initially proposed." RTE

The one hour correction at the end of October returns the 24 hour cycle (clock) to its original position within the sunrise/noon/sunset cycle where the symmetry in the length of time between natural sunrise and clock noon becomes symmetrical once again with clock noon to natural sunset, hence this means clocks move forward in October. When DST is applied, a one hour asymmetry is created between natural sunrise and clock noon while the 'longer evenings' are created by the greater period of time between clock noon and natural sunset with noon as the anchor for the entire spectacle.

DST and time zones are flexible extensions of the Latitude/Longitude framework which anchors the 24 hour day in every rotation to noon and the central/stationary Sun.

In terms of weather, there is just noon and a rise in temperatures afterwards for a number of hours just as there is astronomical noon on the June Solstice with temperatures rising afterward. In this respect, there can be no meteorological seasons versus the astronomical seasons as the Met Eireann forecaster cheerfully announced at the lunchtime forecast by declaring this is the last day of summer. In the proper scheme where midsummer is defined by the dynamic traits of the Earth, the beginning of August represents the beginning of Autumn if people choose to split the orbit of the Earth into four seasonal parts by hemisphere just as the day is broken into sunrise, noon and sunset within the 24 hour cycle.

Seeing I can no longer post links, the 'timeanddate' website showing sunrise/sunset times for any given location will demonstrate the DST asymmetry between the 24 hour cycle and the natural cycle and why clocks go forward in a few months. It is supposed to be enjoyable and so what if the experts go quiet, this is the way it has been for decades as people become familiar with a more productive perspective. Everything else is small and petty.

Orion402

Just as the sunrise/noon/sunset cycle provided the basis for constructing accurate clocks with its equable hours, minutes and seconds, then so does midsummer on the June Solstice provide so much culture on this island by way of its calendar constructed around human activity and the motions of the planet.

The 3,600 BC Listogohil monument in Sligo is aligned to Samhain where societies on this island broke the year into the dark half from November 1st to May 1st and the light half for the following 6 months along with their respective festivals of Samhain and Bealtaine while Samhain took priority as being the start of the New Year. It coincided with the end of October or Deireadh Fomhair which means ' End of Harvest' and provides a beautiful placement for the highly developed 3,200 BC December Solstice alignment at Newgrange as a once-off world heritage site.

The topic of explaining DST properly ties in with the seasons and the ability to put the annual cycle in context of weather, temperatures and the length of natural daylight arising from the motions of the Earth which orchestrate the whole spectacle. It is not for everyone, that much is clear, however, it is exceptionally rewarding for those willing to recognise that the motions of the Earth (astronomical seasons) dominate just as temperatures follow the path of the sunrise/noon/sunset cycle with astronomical noon as the anchor. I have no issue with the meteorological seasons other than it muddies appreciation of the dynamics responsible for changes relying on the orbital points of the Solstices and Equinoxes and specifically the relationship of the North and South poles to the dark hemisphere of the planet and this is where the real research of our planet and the solar system is.

It is unwise to disturb the ancient heritage of this island even if our ancestors attached superstition to it, not because of the superstition, but because it contains the almost genetic memory of our culture in understanding the great cycles which make life possible.

People should appreciate that when DST is removed, the length of time from sunrise to clock noon becomes symmetrical with the length of time from clock noon to sunset resulting in 'longer mornings'. It means clocks go forward to their anchor in natural noon rather than backwards as the less informed imagine.

This is not a trivial issue and neither are the Solstice/Equinox markers for the orbital position of the Earth, which influence weather conditions across the planet and as a lead in to planetary climate proper. It is not for everyone as the reactions in this thread indicate but as this is really the first time DST has been explained in terms of both timekeeping and our planet's motions, especially rotation, derision is expected from some quarters.

Orion , wasn't your last post locked for utter jibber jabber?, this one isnt much of an improvement imho.

Plus, there is an astronomy forum.

Orion402

To be fair, none of this is presented for academics and their cheerleaders who surround them, it is for people encountering cause and effect for the first time in terms of DST and daily rotation to which the 24 hour and Lat/Long systems are anchored. Nobody else has done it before for very specific reasons related to the empirical subculture which misused timekeeping for the last 250+ years.

Timekeeping is cyclical rather than linear, so when these fine people show up with graphs and conclusions about future planetary temperature conditions, they neglect the awful conclusions inherited from the original timekeeping misadventure where they attempted to anchor daily rotation to the daily change in position of the stars rather than its home in the sunrise/noon/sunset cycle and the central/stationary Sun.

The reactions are petty, but that is expected whereas the more astute will understand why clocks move forward to natural noon in October and the symmetry between the length of times to sunrise and sunset. Don't disappear the thread like the last one, but let it drift away as is proper and dignified.

Hello hello is there anybody in there,

Orion402

Climate, like timepieces, depends on cyclical motions and especially the interaction between daily and orbital motions. I could dictate that datasets are worthless without first coming to appreciate what planetary climate is within a solar system context and in comparison to other planets but feel that is too drastic and rude.

I accept this audience is not suitable for technical discussions on either planetary motions, Earth sciences or timekeeping and there I leave it.

Orion402

There was always a slim chance that somebody with the necessary acuity would be able to deal with the technical details and for this reason I reiterate that nobody here is at fault and can safely go back to whatever they are doing.

The misadventure with timekeeping in the late 17th century which led to empirical modelling by experimental theorists is that they consider timekeeping to be linear, hence they project conclusions and graphs to support their perspective on climate that way while ignoring the cyclical principles which define climate and timekeeping. Cause and effect were lost this way when the Royal Society theorists attempted to shift the reference for rotation away from the stationary/central Sun along with the day/night cycle and appealed to the daily change in the position of the stars in a framework called RA/Dec but better known as the 'clockwork solar system'. It ultimately leads to the most absurd conclusion ever proposed through a linear perspective of timekeeping-

" It is a fact not generally known that, owing to the difference between solar and sidereal time, the Earth rotates upon its axis once more often than there are 24 hour days in the year" NASA /Harvard

The framework of RA/Dec occupies the same status as DST and Time Zones as flexible extensions of the primary framework which keeps rotation anchored to the sunrise/noon/sunset cycle by way of the 24 hour and Lat/Long systems. When people decided to diverge and make RA/Dec the primary framework, then cause and effect was lost and unfortunately remains so until a great deal is cleared up.

I accept, with some dismay, that this audience is unsuitable for what is necessary to explain what DST represents in terms of timekeeping and planetary dynamics as a point of departure for considering other more developed topics. No need to disappear the thread like the last one.

Didn't you say you were done here?

There are plenty of people with technical acuity, but nowhere near enough imagination to know what the hell you're talking about or what your point is.

M.T. Cranium

Daylight saving or "summer time" schemes were brought in when our societies had short enough working days to allow large numbers of people to seek leisure activities in the evening hours, and it was noted that the existing time zone system (which didn't start off with this feature originally) had left lots of time in the summer mornings to move sunrise one hour ahead which would give the evenings an extra hour of daylight relative to the working day and the average person's routine supper time. So it gave that extra hour to go to a park with your family, or play golf without running into darkness while still on the course, and there was no disruption to mornings because the Sun just rose at something like 5:00 a.m. instead of 4:00 a.m. ... which was early enough to suit almost all walks of life, 90% of which were sound asleep until well beyond that.

Daylight saving or daylight savings (both terms are in common use) schemes were first proposed in the early 20th century and were implemented in a few places partly in an effort to conserve coal in the first world war. Some jurisdictions that had implemented it then revoked it around 1919 and brought it back for the second world war, after which it proved more popular and was retained.

Just for clarity, I should say that before there were the 24 (and a few extra) time zones, various places set their clocks as the local authorities determined was best, so you could have a situation where one town had their latest sunsets at 9:30 p.m. and another town not far away had a different setting so the latest sunset might be 10 p.m. And in theory any of those local jurisdictions could have had a daylight saving time but it was not a practice anyone proposed or implemented. The time zones were proposed in the late 19th century and it was about two decades later that people started experimenting with daylight saving schemes. Farmers were the most opposed to it, although all they had to do to adjust to it was to schedule tasks an hour later during the DST periods (for example, cows might need to be milked at a given time of day on the solar based standard time, so they would continue to do that when the clock read an hour later during DST). Movie companies didn't like it because some people would rather not attend movies while it was still daylight but their business wouldn't operate as well if they moved their opening times back an hour.

It should also be mentioned that "solar noon" is an approximation of something more complicated, time could be set so that on a given day of the year, at the central meridian of time zones, the sun was at transit (due south) at noon, but that would not be the case every day of the year (see the concept of analemma related to sundials if you don't already understand why, it has to do with our orbital plane and the tilt being in three dimensions rather than two). Also anywhere not on the central meridian would have an earlier solar transit if east, and a later one if west, of the defined solar noon position. Irish people know this because of your later sunset times relative to England at the same latitudes.

In fact, the defined moment of time that is currently noon (1200 GMT or displaced versions in various time zones) is generally a bit earlier than solar transit which on most days of the year is closer to 1 p.m. standard time than noon -- this was a flaw that was a sort of first approximation of the DST concept to move sunset later in the first place. The only reason it is noon at noon is that some governing body says so, not because some observatory is tracking solar transits and verifying that on a certain date the transit has been at noon. The analemma part of the complexity means that the timing of solar transit varies over about the span of an hour during the year so some parts of the year have even longer delays from clock noon to solar noon. Others almost line up. That whole business shifts one hour later with daylight saving time (solar transits are closer to 2 p.m. than the 1 p.m. you might expect).

And once daylight saving time was widely adopted, it naturally then occurred to people (in the political process, by then this had very little to do with science) to ask, well since the daylight saving time is so big an improvement, why not extend it to winter half year and be done with the time changes? In other words, just redefine the 24 time zones (actually it's more because there are some half-hour displaced time zones, for example, Newfoundland is 0.5 hours ahead of Atlantic Standard Time) or reset Greenwich Mean Time from which they all draw their differentials. But then it was noted that such a change, while bringing a welcome extension of daylight around the end of the work day and the trip home for many people, would also extend morning darkness which many found depressing as they got up and prepared for their day, into the full commuting period (at least from November to January).

So that never caught on with many people and most jurisdictions never changed their original system of the late autumn and early spring time changes. The UK (I read, I didn't remember this from my youth) tried out permanent "summer time" from 1968 to 1971 but people hated the dark winter mornings and it was switched back to the original plan. Other countries have gone through it as well. A debate has begun on the west coast of North America where four states (including inland Nevada) and the province of BC (other than its eastern region) are in the Pacific time zone and some states wanted to have perennial daylight saving, in other words, they wanted to be on Mountain Standard Time all year. It lost momentum when people realized that if all five jurisdictions didn't change at the same time, there would be a checkerboard pattern of minor time zones leading to business disruptions as Bob in Las Vegas failed to remember that Lou in Seattle was no longer in the same time zone.

Time zones can be confusing in North America. A few counties in eastern Oregon are on Mountain time because Idaho is on mountain time and they get their TV reception from Boise and do most of their big shopping there. Arizona stays on Mountain standard time all year, and having visited there I can verify that it means that sunset is freakishly early in June and July, like it's almost totally dark by 8:30 p.m. (MST) at that low latitude. Saskatchewan is in the central time zone but does not do daylight saving time because they are so far west in the central time zone that they get the required long evenings in summer from standard time. But Manitoba on central time does put their clocks forward in spring and back in autumn. That must be confusing for people near the border of those provinces. I would find it very confusing to live in a place like Newfoundland where the time zone is set up three and a half hours behind Greenwich but otherwise operates the same way with time changes. These time zones also extend into the very far north where basically it doesn't matter what time you say it is because there is only one long day and one long night in a year.

Frankly, I don't care much about this entire topic, because I'm retired so I live on sun time anyway, I don't have to rush out to the golf course after a quick bite to eat as in former days, I just go when I want to go. If only everyone would follow that example, right GL?

The removal of DST at the end of October means that clocks go forward even as the hour hand is adjusted backwards by one hour and likewise clocks go backwards in Spring as the hour hand moves forward by one hour. For those with intellectual and perceptive integrity, clocks can only go backwards or return to their normal anchor in the sunrise/noon/sunset cycle.

It is not presented for those who lack the technical acuity to appreciate the connection between cyclical timekeeping and the cyclical motions of the Earth and especially the latter, which determines the day/night cycle through rotation, the annual cycles as a combination of daily and orbital motions and finally planetary climate which is defined as the rate of change in atmospheric and surface conditions across latitudes as the planet orbits our parent star in comparison to other planets.

Presently, there is an asymmetry between natural sunrise and clock noon in contrast to clock noon and natural sunset (longer evenings) so clocks go forward to their natural position at the end of next month when the symmetry between sunrise and clock noon along with clock noon and sunset is restored. I would demonstrate how this is derived from the Equation of Time by Huygens through a link, but people are petty and put all sorts of obstacles in the way by preventing links being posted.

As for those who throw the kitchen sink at DST, I have to smile as it is nothing I haven't seen in so many productive topics over the years as they don't reach the level of perceptive faculties needed to consider these topics in a satisfying and calm way. I say to them as to others, these things are not for everyone.

Apart from the sycophants, never mind the bluffer making a fool of himself, in October the clocks go forward and there is nobody else to argue against the technical details, as expected. The explanation is correct and that is all that counts.

Now I repeat this once more, this is the wrong audience for discussing why natural noon and clock noon return to normal when DST is removed, everything else reflects deficiencies in understanding that principle that the length of time between sunrise and noon becomes symmetrical with noon and sunset in terms of timekeeping once the one hour moves back one hour next month.

In terms of adjustment, the removal of DST is one of the most influential during the year as its appearance in Spring so now, for the first time in history, it is explained properly to an audience that I now understand is unsuitable for discussing anything. It reflects on yourselves as the explanation is correct as is its definite conclusion that despite the belief that clocks go back in October, they actually go forward.

In asking to leave the thread to drift without further comment rather than make it disappear as the last thread did, as the one consolation contributors have to save their dignity, it appears they would rather cling to a bluffer out of his depth and be seen to be so. It doesn't matter, people apart from adoring cheerleaders, would already know bluffing when they see it.

The people at Met Eireann should be ashamed of themselves, but then again, when the standard is so poor they can't be entirely held responsible for not knowing why timekeeping and the motions of the planet matter in terms of climate and meteorological effects.

M.T. Cranium

So do you change your own clocks in the opposite direction to everyone else?

I suppose you could go forward in spring and forward in autumn too, if you went forward 11 or 23 hours depending on what kind of clock.

Or maybe you live in the southern hemisphere. They change in the opposite directions at same times of calendar year although they do what we do from their seasonal perspective.

You have certainly proven a point, there is no debate about that. It may not be the point you had imagined however.

John Creedon's documentary was on RTE at lunchtime and there was an old gentleman farmer taking weather measurements as he did for many years and sending them on. He said the whole thing came naturally to him and that is the difference between those who can come to the satisfying conclusions as opposed to those who struggle and can't hide it with extraneous nonsense.

It should remind everyone that weather is a cultural thing on this island given the deireadh fomhair at the end of October begins the New Year on this island (Samhain) celebrated for as long as inhabitants worked with the changes in daylight and darkness. It's all the more surprising how a straightforward explanation of removing DST which returns the symmetry between natural sunrise and clock noon with clock noon and natural sunset when clocks move forward to their normal position linked to noon at the end of October is met with such silence. It means moving the hand back one hour, but within the structure of daily rotation and timekeeping, clocks move forward.

I do not have time to waste on bluffers and their figure-8 wandering Sun (analemma), the principles of timekeeping which anchor rotation to noon and the central/stationary Sun are fixed by a symmetry between sunrise and sunset with the natural inequalities evened out to connect the variable lengths in the full noon cycle with the equable 24 hour clock when the system first emerged with reasonably accurate clocks-

" At the rising and setting of the Sun, when it is half above the horizon, mark the time of the day, which the watches then show; and though you have in the mean time sailed on, it is not considerable. Then reckon by the watches, what time is elapsed between them, and add the half thereof to the time of the rising, and you shall have the time by the watches, when the Sun was at South; to which is to be added the equation of time the present day by the table. And if this together makes 12 hours, then was the ship at noon under the same Meridian, where the watches were set with the Sun. But if the sum be more than 12, then was she at Noon under a more Westerly Meridian: and if less, then under a more Easterly; and that by as many times 15 degrees, as that Summe exceeds or comes short hours of 12: as the Calculation thereof hath been already delivered. " Christian Huygens, Concerning the Use of Pendulum-Watche for finding the Longitude at Sea

DST, time zones and RA/Dec would normally be useful extensions of the 24 hour and Lat/Long systems, however, in this era where few can put DST in context of daily rotation, be it ever so straightforward and simple. It comes down to being a cultural thing rather than meteorological or astronomical as the effects are so pronounced at our latitude on this island. It is for these people who know the end of autumn occurs at the end of October and is a cultural thing backed by technical details stretching back to antiquity, that clocks go forward in October despite the hour hand moving backwards.

The old farmers knew enough not to vandalise old monuments and likewise the cultural heritage of this island which is far more powerful and more intimate than present company imagine, including the divisions of the seasons and why they choose the invariant cycles supplied by the motions of the Earth rather than weather.

(I should add that nobody needs to deal with how the averaging process of the natural noon cycle transfers to constant rotation and the Lat/Long system, although it is helpful to appreciate how things were done in order to anchor rotation to the day/night cycle)

" So do you change your own clocks in the opposite direction to everyone else?

You or someone else can post a timeanddate link for Dublin sunrise/sunset times presently seeing I can't do it because the privilege has been removed.

On this day with DST in operation, pick up the Sun and move it back one hour reflecting 'longer evenings' where clock noon to sunset is longer than clock noon to sunrise. When DST is removed at the end of October, the symmetry returns as clocks move forward by one hour. It is accurate and that is all you need to know unless someone else cares to explain why clocks move backwards in Spring towards sunrise. I would be pleasantly surprised when it eventually happens, if not here then elsewhere.

Next month is Deireadh Fomhair or 'end of harvest' signalling not only the beginning of winter, but the start of the New Year celebrated 5,600 years ago at Listogohil by a community who lived with the land and its weather. It is also when clocks go forward to the symmetry between the length of time from clock noon to sunrise and to sunset.

Thank you.

Move the Sun back one hour towards sunrise and recognise the asymmetry which accounts for the DST and its application in Spring thereby creating 'longer evenings' from clock noon to sunset. It should become clear why clocks move forward in October even as the hour hand moves backwards by one hour. The extra hour in terms of a clock surfaces as a longer length of time from sunrise to clock noon while clock noon to sunset returns to normal.

Well the poster has had their say, they hide a bit behind obscure semantics but clearly they have a hate on for me because I have some degree of visibility here which they resent, and it seems to be in part because they think I do not appreciate the Irish cultural heritage. That is a bald faced lie which the person can either retract or if they wanted to be courageous enough to reveal an actual identity, discuss in court as I don't feel like being casually defamed for absolute no reason whatsoever.

Somebody can contact me by private message if such information appears, but as I don't expect the person to be that forthright, I think this is the last I will be saying on this subject.

Should this poster or their posted threads remain on the forum, I will be ignoring them from now on. So if anyone wonders what I might have to say about further or future insults, I leave that to your imagination.

I note that the poster tried all this on before as "Oriel36" and was banned from the forum, so I have sent in a request to moderators to repeat that process as I think it breaks the forum charter to come back and try again under a new username. Perhaps a boards.ie total ban would be in order. I imagine the person would try again under yet another name, which will be a tiresome waste of time but nothing I can really influence in any way.

Good bye, I have tried to be civil and have attempted to ask sincere questions and this is the response I get. It is not the first time in my life, not everybody plays by the same set of rules as most of us. They should not expect any special treatment.

The seasons are neither solely meteorological nor astronomical, but rather a part of the Irish culture that incorporates our latitude, our festivals and so many other parts of daily life where we adapt and adjust to seasonal and daily changes in temperature and daylight. The seasonal adjustment of DST has become part of that culture, whether people agree or disagree with it so it is only right that it has been explained properly in terms of daily rotation along with the 24 hour system and the Latitude/Longitude framework on which accurate clocks were built.

Irish people are generally fair so thanks to the other contributor and his courage for supplying the link which makes it easy enough to understand how the length of daylight from clock noon to natural sunset increases when DST is applied. People of this island inherit a very old heritage and traditions that do not go away because less capable people are dominant presently and that includes an extension of this topic which defines the seasons through the Solstice and Equinox points. In short, understanding timekeeping properly is also to understand the different motions of the Earth and their effects on weather through the cyclical variations across an orbit of the Sun.

The explanation for DST in terms of the technical details of the breaking of the natural symmetry between clock noon with sunrise and sunset is new, so the proper explanation would appeal to those who live with the land and daily business relying on daylight. It means as the hour hand of a clock moves backwards in October, the 24 hour system moves forward to its home tied to natural noon with each rotation.

I don't have time for nuisances chattering about non-existent libel or banning as it distracts for the purpose of this thread to promote discussion rather than kill it. These people are petty and seen to be so.

My "courage" for supplying the link? I'm not sure what type of crusade you think you're on but each post takes you further away from the relatively sane world the rest of us live in. I'm not sure why you have beef with someone who lives outside Ireland and where that irrational hate is coming from. I'd hazard a guess that whatever hatred you have for him is dwarfed by the hatred that most of us now have for you. To me you seem to be the textbook definition of a troll, but one of the weirder ones. The sooner the better this circus comes to an end.
