Daylight Saving Time will end at 2 a.m. Sunday, and revert to Standard
Time , giving you an extra hour of sleep.
It's also the perfect time to change the batteries in your smoke alarms and carbon monoxide detectors.
If your clocks, computers or VCRs jumped the gun by automatically
adding an hour last weekend, that's because their internal computer
chips were programmed before changes were put into effect by the Energy Policy Act of 2005.
Those appliances should be back to showing the right time again on Sunday.
The legislation extended daylight saving time by four weeks, lasting from March 11 to Nov. 4.
Lawmakers hoped that the change would reduce energy costs by making better use of daylight hours.
Though codified by Congress in 1966, DST is still not observed in
Hawaii, American Samoa, Guam, Puerto Rico, the Virgin Islands or
anyplace in Arizona except the Navajo Nation Reservation. Worldwide, it
is observed in about 70 countries.
After
the time change this weekend, the U.S. Department of Energy will
conduct a study to determine how much, if any, energy was saved and
report that information to Congress.
Next year, Daylight Saving Time begins March 9 and ends Nov. 2.
