Earlier daylight-saving time takes effect tomorrow

March 10, 2007|By The Denver Post

Daylight-saving time comes early this year - tomorrow - because the federal government decided that moving it to March could save energy. Clocks should be moved forward one hour at 2 a.m. tomorrow.

Here's what you need to know to adjust your electronic devices:

TVs, VCRs, DVD players

Since most consumer-electronic devices are programmed to switch to daylight-saving time in April, users will have to manually reset clocks on TVs, VCRs and DVD players. Depending on the device, you may need to reset it again in April if the clock automatically springs ahead.

Cable or satellite set-top box: Comcast, DirecTV and EchoStar, which runs the Dish Network, say their set-top boxes will automatically change to the new time.

Home computers

Windows-based PCs: Users with the new Vista operating system will not have to make any manual changes. Users of Windows XP Service Pack 2 should let Windows automatically update the necessary patch. A tutorial is offered at www.microsoft.com/windows/timezone.mspx.

Users of the new Outlook 2007 do not have to do anything. Older versions of Outlook need to download the time-zone data update tool from the Microsoft Web site.

Apple is providing updates to users, depending on the Mac OS versions they're running. Information can be found at http:--docs.info.apple.com/article.html?artnum305056.

Cell phones

The time display on cell phones will change automatically as providers make time changes on a central network.

For BlackBerrys, Treos and other smart phones: Verizon, consult the manufacturer's instruction guide and update or patch the device; Cingular users will have to update software on certain smart phones at https:--www.cingular.com/support; T-Mobile's Web site lists devices affected by the change at http:--support.t-mobile.com/ knowbase/root/public/ tm23412.htm.

Sprint offers a patch for several devices at http:--support.sprint.com/doc/sp10392.xml.
