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. More...

Q: I have software downloaded that lets me ping to the atomic clock in Denver. When I do it keeps putting my clock back to standard time. Then I have to reset manually. What's the problem?

A: Thank you for your message.

Our programs use the time zone settings specified in Windows. If you install the Windows update released by Microsoft in order to solve the issue with the new rules of switching to the daylight saving time, our software will also work correctly.
