Daylight savings time starts today

Daylight saving time went into effect at 2:00 a.m. on Sunday morning.

It was a big night at the Ferry Building where the most famous clock in San Francisco resides. The clock motor was shut off and a 3-foot pipe bar had to be pulled by a worker to move the pipes forward.

Workers at the Watch Shop in San Francisco took on a massive job to reset all the watches. Daylight savings time is a federally mandated program to save energy, but one recent study showed it increases energy demand.

PhD student Ryan Kellogg works for the University of California Energy Institute and he says this debate over daylight shouldn't be about energy.

"Day light Savings time really doesn't belong in an energy policy debate. It's more of a debate about lifestyle choice, whether we prefer to have daylight in the evening or in the morning," says Kellogg.

American Council for an Energy Efficient Economy says daylight savings time saves $329 million dollars in energy cost. Shop owners like it because more people are out and about and walking the streets, but they concede it has more to do about weather in the spring and summer months than the time change.
