I arrived in Swansea-Uk in Jan 06 and on the 26th March we were summoned to push our clocks 1 hour ahead. What is the scientific basis for this?

It's called "Daylight Saving Time". It is believed to save electricity by prolonging the day with one hour.

Judge for yourself based on this: Time is a MAN MADE construction. That is, it is not a natural element in life. For those of you who would argue, please answer how it can be set back and set forward (daylight's saving time). If it were natural you wouldn't be able to limit it to the watches you wear or the clocks on the wall. It would be beyond any human control and it would be very hard for anyone to grasp the concept and explain it. As it is, we CAN explain it and grasp it, therefore, it is not natural.\n\nSo my answer is no.\n\n\n\n\n\n\n\n\n\n\n.

Adam S is almost right.  You would need to dial 011 to call out from the US in order to call London.  The rest of his info is correct.\n\n**edit**\nYou can also go to this site and it tells you what to do\nhttp://www.timeanddate.com/worldclock/dialing.html?p2=136

You may want to take your direction from the "End  Daylight Savings Time" campaign (see link to web site below).\n\nUnfortunately, things appear to be moving in the other direction as an amendment to an energy bill passed by Congress in Aug. 2005, Daylight Saving time will be extended by about a month. Beginning in 2007, Daylight Saving Time will begin on the second Sunday in March and end on the first Sunday in November.\n\nThe sad reality is that both sides in this argument have mired it down with exageration and statistics which cannot be verified. As a result, no rational argument can find a foothold.

Times written in military time (24 hour format) are four digits, such as, 1830Z (6:30 pm) with the Zulu suffix. Note that the phonetic alphabet is used for the letter Z (Zulu). This time is usually referred to as Zulu Time because of the letter assigned to this time zone. \n\nIts official name is Coordinated Universal Time or UTC. This time zone had previously been called Greenwich Mean Time (GMT) but was replaced with UTC in 1972 as the official world time standard changed. While GMT is based on Earth's rotation and celestial measurements, UTC is a based on cesium-beam atomic clocks. The two clocks are rarely more than a second apart as leap seconds are applied to UTC.\n\nSo, Zulu Time is taken from Greenwich in London. On the West Coast of the US, we are 8 hours behind that time

Actually, me too!  I look at the clock all the time-- morning and night, and it's 9:11!  I thought, it's amazing.  I went through a period of about 6 months whenever I looked at the clock, it was specifically that time.  I thought maybe it was just in sync with my biological clock, but I couldn't shake the significance of those numbers.  I'm not sure what it all means-- but I do not believe in coincidences.  It's something worth looking into, definitely.  I'll be interested to find out your results.

Time for you to get a watch.  \nIts 10:33 pm here in Sac California USA

You've likely changed you time-zone, so it is automatically changing each time it links up to the time-server to check.\n\nTwo options:\nFirst double click on the clock in the taskbar.\n*Now you can either disable the time-syncing feature on the "internet time tab", then rest to the correct time, or...\n*You can correct you time-zone on the "time zone" tab.\n\nEither solution should set you straight :)

Does any body really know what time is?  Does any body really care about time?  As I was walking down the street today, being pushed and shoved by people trying to beat the clock, that day, that day.....does anybody really know? Does anybody really care?

I turned my daughter's clock forward today. She was not impressed with me when she eventually realised that she had got up at 5am instead of 6 to go to work. Ha.\n\nAlso have a look at the response OneRunningMan gave to The Kimster  on the same subject.

Sadly, I've actually heard about this before.  I can't believe how much useless junk I put into my head...I'd say pure fiction.  Its just more likely that he was some bored computer geek trying to get some attention.  Its still unclear whether or not time travel into the past is possible.  Based on current science I'm leaning toward the impossible side.  Oh well, 2036 will be here soon enough.  Then we'll know for sure.   ;)

Don't confuse the workings of clocks with the passage of time. Clocks, like any mechanical device, are prone to errors and can fail over time (no pun intended). The passage of time will happen whether we have clock to measure it or not. That makes no difference.\n\nWe now do have atomic clocks that utilize the radioactive decays of heavy elements as a measure of time and they are accurate to a billionth of a second, but even atomic clocks are NOT 100% accurate. So as with any measurements we make in the process of scientific study, there will be errors. But I think in most cases, the accuracy of an atomic clock is more than acceptable.

Actually a good many countries around the world use the 24 hour clock system. Then there isn't a need to say AM or PM, you know whether its day or night. Also the military begins attacks, movements and such on Greenwich mean time, its a town in Britain. And its used so everyone that aware of an operation knows what time it begins regardless of what part of the world they are in.

Neither Observer EXPERIENCES a change. The ONLY way any comparison can be made between the two unmentioned but essential clocks is to bring them together in the same rest frame again: then whichever clock ticktocked the least would be shown to be the one which accelerated and slowed down in their relative travel.

Tokyo Japan time\nhttp://www.timeanddate.com/worldclock/city.html?n=248\n\nCairo Egypt time\nhttp://www.timeanddate.com/worldclock/city.html?n=53\n\nIdeally there is a 7 hour time difference between them wrt GMT. However, since you see Egypt is running at 1 hour daylight saving time, the time difference now is 6 hours!\n\nHope this helps :-)

Absolutely! It is ridiculous that it is fully dark at 4PM in the winter where I live, yet it doesn't get dark until 10 PM in the summer.  We could at least do away with some of the gap by eliminating the artificial difference by going on daylight saving time permanently.

Signed with the following comment...\nYa know there's 6/6/2006 and 6/6/1906 and 6/6/1806 and there will be 6/6/3006 and 6/6/4006.  Why is this so special?
