Daylight saving time begins, have you set your clocks ahead one hour?

MILWAUKEE -- If you're behind on your sleep, you may have a harder time than usual catching up this weekend. That's because daylight saving time began at 2 a.m. Sunday -- and now you can officially move your clocks forward one hour.

You may be used to springing forward in April. That all changed in 2009, when the Energy Policy Act of 2005 took effect, moving the daylight-saving practice of "springing forward" from the first weekend of April to the second Sunday of March. It also changed the policy of "falling back" to the first Sunday of November.

This is also the time of the year when you're urged to change the batteries in your smoke detectors and carbon monoxide detectors. It's a small price to pay for security in your home.
