Daylight Saving Time

[S485122]

As far as I know there are serious doubts about the power savings induced by DST. DST is a nightmare for parents of little children, dairy farmers and people having to have schedules match among others.

For my part I prefer to go to work in the morning in daylight, in the evenings I always go to bed after sunset so I do not mind to much having night start a bit earlier...

Here in Denmark about the same latitude (well depends on where in Britain) its light until 10:45-11pm with just 1 DST at midsummer.

My mom said Denmark had year-round DST during the war, but not sure if it was double DST.

That figures: latitude ~same as Scotland, longitude ~10 degrees east,
CET = GMT+1.

Why? So it's dark when they wake up to get ready to school, but OTOH it's still light when they come home from school.

dairy farmers

Why? Aren't they the ones who get up long before sunrise year-round?

and people having to have schedules match among others.

Huh?

You go to bed at 5pm in the winter?

ewmayer : Why? So it's dark when they wake up to get ready to school, but OTOH it's still light when they come home from school.

Children tend to stick to their natural rythm and they will go on waking up at the same "astrological time" whithout respect for the official clock of their country.

dairy farmers

ewmayer : Why? Aren't they the ones who get up long before sunrise year-round?

cows and goats do not change their natural rythm as easily : it means the farmer will have to do their daily tasks ignoring the time change, but supplierst, customers and social relations will change will not.

and people having to have schedules match among others.

ewmayer : Huh?

Try maintaining matching train or bus connections accross countries some of whom change their time and others don't.

Not at sunset, after sunset. I go to bed after 17:00, after 23:00 to be more precise and at that time it is always dark under my latitude.

Children have problems getting up before sunrise anytime of the year, DST or no.

Dealing with timezones is a common occurance. It used to be worse when every little village had their own time. Some of the US states and some parts of others don't change. Your mobile phone should deal with the change without a problem. And if you use a GPS nav, same thing. Printed air travel iteneraries always reference the local time, not the time of the departure or the arrival. So on a ticket with a stop over, there may be 3 time zones, but the times are listed in reference to the city that the traveler is in, thus making it simpler and avoids confusion when booking other services.

I seem to have myself expressed badly indeed. What I meant is that all those different DST schemes are a nightmare for people having to establish the schedules of airplanes, trains and so on, not so much for the people using them, they always have to cope with long waits between connecting fares ;-)

Jacob, all your clarifications above appear to be further arguments in favor of "pick one time scheme and stick with it year-round" - meaning the decision then becomes which of the 2 schemes one's country alternates between during the course of a year to use. I bet if we polled the citizens of a typical country as to whether they would want to stay on the scheme giving them an extra hour of daylight in the morning or the evening, the overwhelming majority would choose the latter.

Edit: Poll added.

Indeed.

In particular:
<<
British Summer Time was permanently in force during the
Second World War from February 1940 until October 1945 and again
from February 1968 until October 1971.
Double summer time was in force from 1941-1947 except for 1946.

I knew we had been on permanent DST for a time since WW2. It
coincides precisely with my time at Oxford University. Should
have remembered that

I am keeping my daily commute schedule as if it were still Daylight Saving Time - have to cross several very busy streets between the office and the bus stop, and doing so will allow me to do so in the evenings while there is still a bit of daylight remaining. So instead of being in the office from ~9am-6pm most days, it'll be ~8am-5pm.

Oh wait, this would all sound much more exciting if embellished with islamic-militant-style rhetorical flourishes - let's see:

"The insurgency against the debauched Western standard-time crusaders has begun ... the streets shall flow with the blood of the anti-evening-twilight infidels..."

Alas, evening TV schedules are determined by the lackeys of the aforementioned standard-time infidels, so we'll whether I can keep it up 'til spring.
