Time to fall back -- say goodbye to daylight-savings time this weekend. Clocks shift back one hour at 2::00 am Sunday -- local time. That will give an extra hour of sleep to most people tomorrow night -- and an extra hour of work to those who work the overnight shift. The change to Standard Time also means it`ll be dark an hour earlier on Halloween, calling for extra caution on the part of drivers and those watching children on their candy rounds. Officials say this is also a good time to change the batteries in your smoke detectors. Daylight-saving time returns in April.
