Time to change clocks, spring forward

It's time for a traditional rite of spring, setting the clocks forward for daylight saving time.

Officially, the change comes early Sunday morning, though most folks are likely to reset their clocks before going to bed Saturday night.

It's also a good time to put new batteries in warning devices such as smoke detectors and hazard warning radios.

Some parts of the country don't observe daylight saving time. Those include Hawaii, most of Arizona, Puerto Rico, the Virgin Islands, American Samoa, Guam and the Northern Marianas.

Daylight saving time ends Nov. 6.
