Do we really need to move our clocks back or forward an hour twice a year?

Last year, California lawmakers narrowly defeated a bill that would have gotten rid of the tradition known as Daylight Saving Time (DST), but the lawmaker who wrote that bill is taking another swing at the idea this year.

Rather than simply eliminate DST, the new bill by Assemblymember Kansen Chu (D - San Jose) would give the Legislature the power to change its dates and times by a majority vote. Or, lawmakers could vote to get rid of DST altogether and keep the state in the Pacific time zone all year-round.

The proposal failed last year because lawmakers on both sides of the aisle were concerned about the affect on farmers's harvets and the idea of California businesses being four hours behind their East Coast counterparts.

DST starts at 2 a.m. on the second Sunday of March, and ends at 2 a.m. on the first Sunday of November. Under federal law, states looking to do away with the clock changes need approval from the U.S. Department of Transportation. Chu's bill would also require a statewide vote before DST goes away.

Seventy-six countries and most of the United States use DST. Hawaii and a majority of Arizona are the only states that have eliminated the practice.
