It's time once again to spring forward to daylight-saving time.
For most of the nation, the official change occurs at 2 a.m. Sunday, although most probably will change their clocks before hitting the sack Saturday night.
Folks who forget will be an hour late for church, work or other events Sunday.
Daylight-saving time lasts until Oct. 27.
Safety officials suggest the annual ritual also is a good time to change batteries in smoke detectors to ensure they will work if needed.
Some parts of the country don't observe daylight-saving time. Those include Arizona, Hawaii, the part of Indiana in the Eastern time zone, Puerto Rico, the Virgin Islands and American Samoa.
