    Daylight Saving Time gives us the opportunity to enjoy sunny summer evenings by moving our clocks an hour forward in the spring.

    Yet, the implementation of Daylight Saving Time has been fraught with controversy since Benjamin Franklin conceived of the idea. Even today, regions and countries routinely change their approaches to Daylight Saving Time.Most of the United States begins Daylight Saving Time at 2:00 a.m. on the second Sunday in March and reverts to standard time on the first Sunday in November. In the U.S., each time zone switches at a different time.The official spelling is Daylight Saving Time, not Daylight SavingS Time.The main purpose of Daylight Saving Time (called "Summer Time" in many places in the world) is to make better use of daylight. We change our clocks during the summer months to move an hour of daylight from the morning to the evening. Countries have different change dates. Glide your cursor over the map to see how changing the clocks affects different latitudes.A poll conducted by the U.S. Department of Transportation indicated that Americans liked Daylight Saving Time because "there is more light in the evenings / can do more in the evenings." A 1976 survey of 2.7 million citizens in New South Wales, Australia, found 68% liked daylight saving. Indeed, some say that the primary reason that Daylight Saving Time is a part of many societies is simply because people like to enjoy long summer evenings, and that reasons such as energy conservation are merely rationalizations.According to some sources, DST saves energy. Studies done by the U.S. Department of Transportation in 1975 showed that Daylight Saving Time trims the entire country's electricity usage by a small but significant amount, about one percent each day, because less electricity is used for lighting and appliances.

    It's a good point - looking into my crystal ball, the start time won't change, bad light will end play early 5 out of 5 days (assuming we get in 5 days), the shadows on the field will be rediculously long, and Brian and the rest of the commentry team will be moaning about this very issue - with the usual, tv audience size, money rules etc, etc being put forward as the excuses as to why not. As usual we will be none the wiser and everyone wins except the fans! Right on NZ cricket way to promote the game! And btw, what's with the coverage being on Skysport Channel 3 for crying out loud?! I shake my head.....our talent pool is small enough without making the game inaccessable to our future cricketers.

    Here's what I found on www.weatherbug.com:

    Daylight Saving Time

    By WeatherBug Meteorologists

    On Sunday, March 9, at 2 AM clocks all across America will be turned ahead ("spring forward") one hour as we observe Daylight Saving Time (DST).

    What you may not be aware of, however, is how daylight saving originated and the connection it has to weather.

    The main idea behind Daylight Saving Time (DST) is to allow people and businesses to utilize daylight more effectively. More specifically, turning the clocks back in the fall and ahead in the spring helps to conserve energy.

    According to many historians, the original idea for DST originated with none other than Ben Franklin, who was known for his colorful and often practical ideas in the realms of science and public policy.

    In 1784, as he approached the end of his term as an American delegate in Paris, Franklin penned "An Economical Project," a discourse on the merits of natural versus artificial lighting. He included several humorous laws or ideas that the city of Paris could enact to conserve energy and make better use of daylight.

    Others adopted the idea in Britain and this was the first country to put DST into effect starting in 1840 with London railroads. By 1855 a large majority of Britain's clocks were set to DST.

    Much later, the U.S. government created a law putting daylight saving time in effect during World War I and World War II. Between 1945 and 1966, however, there was no U.S. law to enforce daylight saving time.

    However, by 1966 daylight saving time was in use by over 100 million Americans due to local laws and customs. Many of these individuals were farmers, who felt their productivity benefited from the extra daylight in the morning during the spring and summer.

    In 1966, the Uniform Time Act was passed, setting up a system of uniform (within each time zone) Daylight Saving Time throughout the U.S. and its territories.

    Mid-fall is a natural time to turn the clocks back in the U.S., since it is a time when home and business owners are switching from air conditioning to heat.

    The specific "turn back the clock date" that saves the most energy year-to-year depends on weather conditions in a particular country. In the U.S. the clocks are always turned back in mid-autumn and turned forward in early spring.

    Many other countries use daylight saving time as well, including all of Europe, Australia, New Zealand, Brazil, Chile, Israel and Egypt.

    In the southern hemisphere countries like Australia, Brazil and Chile, the dates are reversed because their seasons are the opposite of the northern hemisphere's. Thus clocks are turned back in March or April and forward in September or October.

    You can use WeatherBug to track sunset and sunrise times for your location before and after Daylight Saving Time.
