Why was daylight saving time started? Here's what you need to know.

Clocks roll back an hour this Sunday — to the chagrin of many Americans.  

For more than 100 years, proponents and opponents of daylight saving time have argued over whether to keep observing the twice-yearly changing of the clocks, but many don't know how or why the U.S. started the custom in the first place. 

The origins of daylight saving time have been attributed to various people and reasons. Fingers are often pointed at farmers as the originators of the practice so they could have more daylight, but farmers didn't necessarily support the time change when it was adopted in the early 20th century. Some have said Benjamin Franklin started the practice back in 1784 when he wrote a satirical essay for the Journal de Paris proposing regulations to ensure early risers.
