DST ClockBefore this year, the beginning of Daylight Savings Time, also known as “Spring Forward”, has always been on April 1st. This year, everything has changed: it will be on March 11th.

The end of Daylight Savings Time, also known as “Fall Back”, has also been rescheduled to another date. In previous years, it used to be on October 28th. This year, it will be on November 4th.

Normally, DST would not be a concern to us System Admin guys, however, many of our systems are not aware of the changes that were made to Daylight Savings last year by the Canadian and American governments.   Many of our computers will need to be patched so they can adapt to the new DST.

All major manufacturers (From Adobe to Research In Motion) are supplying patches to their customers to fix this issue.  These changes will also affect Blackberry’s and other mobile devices used to schedule meetings and appointments.

A provision of the U.S. Energy Policy Act of 2005, extends Daylight Saving Time (DST) in the US by four weeks, beginning in 2007. Systems and applications that process dates and times using the U.S. DST rules will be affected by this change.

Fortunately, there’s a great website ( out there that has been created to help those of you in need of guidance to address any DST issues you might face in your environment. Check it out.
