Here we go again. It's time to go messing about with our clocks this weekend. Of course, this time around, we get to set our clocks back and hour which means we get an extra hour of sleep on Sunday. Well, at least that's the way it works in theory. Personally, I'm ready for all this clock changing to come to an end. Especially in the spring, when we lose an hour!

The whole idea for Daylight Saving Time (DST) came from Benjamin Franklin. Back in 1784, Franklin came up with the idea thinking it would help farmers to have extra time to work and "save daylight." At the time, Franklin was Ambassador to France, and he later published the concept of changing clocks to fit the season in the Journal of Paris.

The actual practical application of DST didn't really get tested until Ol Ben was long gone. It was roughly 100 years later, in 1916, that Germany used DST to conserve fuel during WWI. It was two years later, in 1918, that DST was put into effect for the first time.

For years now, people have been complaining about the concept of DST, and there has been a move afoot to get rid of the idea. There are already a few states that have opted out of the bi-annual clock change. Opponents of DST say that the changes can "complicate timekeeping and can disrupt travel, billing, record keeping, medical devices, heavy equipment, and sleep patterns."

Currently, about 40% of the world uses DST.
