DST Issues

Standard time was fixed in 1883 to prevent the myriad of short time differences that would result if every locality determined the mean solar time by different meridians, depending on the longitude of the particular place. Lines at every 15° longitude were drawn down a map of Earth to create 24 international time zones differing from each preceding and following zone by one hour. Because of political boundaries, such lines often depart from the strict 15° rule and sometimes zigzag or demarcate ares that differ by half an hour only.

The continental United States has four meridians designated to determine standard times: 75° , 90° , 105° , and 120° west of Greenwich, England. Alaska Standard Time is determined by the meridian at 135° west of Greenwich and Hawaii-Aleutian Standard Time is set at the 150° meridian.

Canada has a total of six time zones: the four that apply in the continental United States and an additional two in the east. Atlantic Standard Time is based on 60° west of Greenwich and is one hour ahead of Eastern Standard Timel Newfoundland Standard Time, based on 52° 30' west, is 30 minutes ahead of Atlantic Standard Time.

The mean solar time determined by the meridian that runs through Greenwich, England (Greenwich Mean Time), is called Universal Time. It is used all over the world in navigation, both air and sea, and for scientific purposes, as in astronomy. From Greenwich, too, longitudes are measured around the world, Greenwich being 0° , called the prime meridian.

A NOTE FROM ME:

Basically daylights savings time is made so that you get better use out of the amount of sunlight that you have. It would create more jobs due to the fact that there are more hours in the day that we could actually work.
