Get a little, lose a little

"Beginning in 2007, daylight saving time (DST) will be extended in the United States. DST will start on March 11, 2007, which is three weeks earlier than usual, and it will end on November 4, 2007, which is one week later than usual .This results in a new DST period that is four weeks longer than in previous years.

Unless certain updates are applied to your computer, the time zone settings for your computer's system clock may be incorrect during this four-week period. In particular, you must make sure that both your Windows operating system and your calendar programs are updated.

Home users: If you use Windows Vista or have Automatic Updates turned on, you may not be affected by the change in daylight saving time. If you want to confirm, follow the steps in the Daylight Saving Time Update Guide.

Time signals can also be heard on shortwave radio or by phone.

"The audio portions of the WWV and WWVH broadcasts can also be heard by telephone.

The time announcements are normally delayed by less than 30 ms when using land lines from within the continental United States, and the stability (delay variation) is generally <>

When mobile phones are used, the delays are often more than 100 ms due to the multiple access methods used to share cell channels.

In rare instances when the telephone connection is made by satellite, the time is delayed by 250 to 500 ms.

To hear these broadcasts, dial (303) 499-7111 for WWV (Colorado), and (808) 335-4363 for WWVH (Hawaii). Callers are disconnected after 2 minutes. These are not toll-free numbers; callers outside the local calling area are charged for the call at regular long-distance rates.

The telephone service is very popular. The WWV number receives over 1 million calls per year, and the WWVH number receives more than 50,000."
