What Time Is It

March 11, 2012 by · Comments Off on What Time Is It 

What Time Is It, Daylight saving time doesn’t save energy — quite the opposite. Back in World War I, when Germany, Russia, and England first adopted daylight saving, the idea was to conserve coal for the war effort. (The United States eventually followed suit in 1918.) If these countries could just stretch out the daylight during the summer, leaders reasoned, then people would use less electricity for lighting. Sounds sensible, right? The problem is that daylight saving no longer seems to be effective on this score.

Here’s a raft of studies on the subject. Most of them find that while households do use less lighting during daylight saving, thanks to the longer, brighter afternoons, they also end up cranking up the air conditioning more, which makes it either a wash or a net loser for energy use. A 2008 paper (pdf) by economists Matthew Kotchen and Laura Grant examined what happened in Indiana when, thanks to a change in state law, all counties suddenly had to shift to daylight saving. They concluded that daylight saving probably costs Indiana about $10.7 million to $14.5 million per year in higher electricity bills and increased coal pollution.

Meanwhile, daylight saving doesn’t seem to impact gasoline use and driving habits one way or the other. Back in 2005, Congress decided to extend daylight saving by four weeks, claiming it would reduce oil use by 1 percent. A subsequent review (pdf) in 2008 by the Department of Energy found that the legislation didn’t appear to have any effect on gasoline consumption at all.

2) Daylight saving time might increase traffic fatalities. There’s also some dispute about whether daylight saving time increases or decreases traffic accidents. On the one hand, the extra hour of sunshine in the afternoon means that more people are driving while it’s still light out. That makes the roads safer, according to a 1995 study (pdf) in the American Journal of Public Health. On the other hand, the sleep disruptions that occur when clocks are moved forward can increase the risk of traffic fatalities during the spring. Back in 1996, researcher Stanley Coren found that traffic accidents flare up in the spring, when we set our clocks forward and everybody’s tired, and drop again in the fall, when we set our clocks back and get an extra hour of sleep.

3) Daylight saving can be bad for your health. Again, some mixed results here. The extra sunlight is good for vitamin D synthesis. But the disruption in sleep patterns caused by setting your clock forward can actually kill people. Here’s the finding reported in a brand new study out of the University of Alabama in Birmingham: “The Monday and Tuesday after moving the clocks ahead one hour in March is associated with a 10 percent increase in the risk of having a heart attack,” says researcher Martin Young. And a 2009 study (pdf) in the Journal of Applied Psychology found that tired workers are at greater risk of workplace accidents.

4) Daylight saving has mixed effects on the economy. Retailers love the extra sunlight — it means that there are more customers around who are willing to go out and shop. The all-powerful golfing industry is also a big fan, apparently. On the other hand, daylight saving can cut into sales for movie theaters and reduce the audience for prime-time television — people go out and enjoy the evening air instead of staring at screens inside.

Atomic Clock

November 7, 2010 by · Comments Off on Atomic Clock 

Atomic Clock, Last night, the most talked about potential fall time change back to 2010 took place shortly after the official time of today has become an hour earlier than it was before. Therefore, if you want to know the exact time U.S. from today, has become important to have an atomic clock, because the actual time that is being displayed on your watch is more likely to be incorrect.

Daylight saving had ended last night and it will be dark when you start your work in the morning. The same will be true at night as well.

The reason for DST is to have more time to save energy during the day. The time will always vary in the fall, depending on which continent you are staying. After this reprogramming of the U.S. current time, people and businesses can take some actual time of your walk outdoors during their lunch hour. In this way, how they will never miss your daily dose of sun shines make your day more healthy.

What is an atomic clock?

An atomic clock helps set the current time according to daylight savings time as any computer or digital software. If a company does not have its own atomic clock, you need to adjust the time twice a year. Moreover, an atomic clock is coordinated with the U.S. when several times a day. There have indoor and outdoor temperatures with Meteorologist barometric sets the time on warm days and freezing as well. Reputable economists say the U.S. time change due to increased demand for atomic clocks, the business done by them and touch nearly 1.7 billion a year.

Official Time

Official Time, Daylight saving time (DST) ends today! Daylight Saving Time, starting in the spring of each year and ends in the fall, actually ends today, November 7.

You should have turned all the clocks (except those computer chip or drive satellite) back one hour.

The date we turn our clocks to end the last Sunday in October, but now ends the first Sunday in November. This year, that date is November 7.

It is also used to start the first Sunday in April, now starts the second Sunday in March. This year, that date was March 14. In 2011, we will move our clocks ahead one hour to save time on 13 March.

Daylight Saving Time was designed to buy more hours of light (and therefore use less energy at night).

Benjamin Franklin was the first to suggest daylight saving time in 1784, but not implemented until 1895.

Correct Time

Correct TimeCorrect Time:At initial look, people will get curious that the word ‘time’ has been trending on the internet.  The initial reaction would be:

Why are they talking about time?

Why is time trending?

Did our time change (how the world revolves)?

Did our Earth’s Axis change again?

People can’t help but be concerned and sensitive these days about what’s happening in the world today.  You can’t blame them for being freaked out every time they hear news about another earthquake that shifted the earth’s axis – yet again!

But, people should not panic because the world is just updating its Daylight Savings time and people would want to know and be updated about the correct time on different countries.  There are many websites that tell the current time as of now and they can be Googled online.  Try to check other sites as well to check for consistency.

Atomic Clock

Atomic clock 1Atomic Clock:Atomic clock idea was first given in 1879 by Lord Kelvin. The practical method was done on it in 1930 by Isidor Rabi. Then in 1949 in US National Bureau of Standards which is now known as NIST invented first atomic clock. The first atomic clock was of ammonia maser. It is world’s most accurate clock. It works is to tell the accurate time with no ambiguity. Atomic clock tells the time better than any other clock in the world. Even it can keep the time better than the rotation of the Earth and even better than the movement of stars in galaxy. This clock works on atom and electrons surrounding it. It calculates the mass of the nucleus and the electrons charge surrounding it.

Atomic ClockDifferent kind of atomic clocks are available. The main functions of all the atomic clocks are same. A basic difference is just the material used in it in different. The elements used inside the atomic clock are detecting the energy level for time calculation in different ways. There are three types of atomic clocks are available:

Cesium atomic clocks: A clock which measures energy level by magnetic field

Hydrogen atomic clocks: A clock that measures time by hydrogen atoms.

Rubidium atomic clocks: It is the simplest form of atomic clock which cans measures the time through microwave frequency in its surrounding absorbing the light in optical.

Atomic clock is not harmful and do not release any kind of radioactive rays. The early atomic clocks were based on masers. In this new era the atomic clock consists of absorption spectroscopy which absorbs the cold atoms in atomic fountains.
