In Australia, many states have daylight saving, they were decided at referendums and people voted them in, - principally so they could enjoy the longer evenings with their family.
In Queensland we don't have it as the north half of the state is dead against it, - too close to the equator, - no benefit, but the southern part of the state keeps trying and may succeed one day.
On the watches point, who wears a watch these days? - we all have mobile phones and they change themselves to local time zones anyway.
The whole thing is a fantasy dreamt up by politicians. Go to Greenwich, London, UK, and you will find the international meridian (it has to reside somewhere, and we thought of it first).
The world is round (360 degrees worth), and so the time zones change so that as you navigate around the world, 12:00 midday is indeed Noon (when the sun is at its peak).
Anything else is as absurd as rounding PI to 3 to make the arithmetic easier.
And, yes, it is absurd that the home of GMT (Greenwich Mean Time) changes its time twice a year).
I think service industries have a tough time with timezones as it is - they either need to be 'on call' for pretty much the whole East-West US timezone working-day-span, or they have to set up local offices that stay in step with PST, EST, whatever. With daylight saving we are talking about shifts in 'latitude time', so we need north-south timezones to allow local optimisation. Other countries have their own issues: Japan, for instance, has a much bigger N-S span than the US.
To decide whether removing this practice, is a good idea or not, we dont need to speculate. Just take a look around. In countries like India, there is no such concept. Schools, work places and institutions change their timings seasonally to make people comfortable. But, since this is not systemic, not everyone is bothered. For example, you dont have to adjust your schedule just because someone living 1000 miles away is finding it hard to reach school while it is dark! Bottom line is that, people adjust to what they feel is comfortable. We should let them decide according to their local conditions instead of implementing a nationwide scheme, on some silly and unscientific pretext.
I absolutely agree! Ditch Daylight Saving and stick to one continous time line. Mankind is always a bit behind. Computers already solved this problem and stick to one universal time, which is globaly available.
In a global world this might be the next step in "time-evolution". It's just a matter of getting used to it.
DST has no effect on the amount of sunlight. It has a vast social effect and that is the point. I knew a couple who tried to stick to summertime one autumn after the time change. They were determined and they managed to do 4 weeks before they joined everyone else.
On a separate point, a single world-wide time won't help. Sure, if I call a meeting at 0900 in some universal time then everyones clocks will show 0900 at the same time, so we all know what 0900 is, no question.
But suppose that the call is between me (UK) and my client (California). The basic problem hasn't gone away - I have to work out when our workdays overlap and schedule the meeting for that time. I would still have to work out a time difference but without the help of the timezones.
So each state (or district?) would evolve an offset: "When do you start your workday?" "1300 universal." Or "What's your workday offset from Universal?" "13".
And then it would be legislated, and then we'd have timezones back again.
And then somebody would observe that in the summer in the UK, an offset of 8 is much better than an offset of 9 and ... and round we go!
