Some clocks fell back one hour for Daylight Saving Time on Sunday morning -- a week early.
In 2007, the time change was moved to the first Sunday in November. But some electronics have the time change information embedded, causing a response on the traditional date, the last Sunday in October.
J.J. Jamieson, utility engineer for Southeast Missouri State University, said Sunday he planned on getting to work early today to correct a few particular timepieces.
But he also acknowledged they may continue to attempt to switch back in response to the date.
He said new electronics will not have this problem.
The dates for changing the time were moved when the Energy Policy Act of 2005 was approved, designating the first Sunday in November as the date to move clocks back one hour, and the second Sunday in March as the time to spring ahead one hour. Times are supposed to be switched at 2 a.m. to minimize the effect on daily life.
One reason for moving the time back by a week is to allow more light for children who go out trick or treating on Halloween. According to a study by the Centers for Disease Control, fatalities among child pedestrians between ages 5 and 14 were at least four times higher on Halloween than any other day of the year.
