What about Day Light Saving and Windows 2000?

Posted by Gerard Louise on Mon, Mar 05, 2007 @ 09:51 PM


According to the Microsoft DST web site, Windows 2000 has passed the end of Mainstream Support, therefore only customers with Extended Hotfix Support can obtain the Windows 2000 hotfix. 

If you are counting yourself (as 99% of small businesses do..) without that "Hotfix Support Agreement", do not despair!  Microsoft will allow you to purchase a kit including all DST update tools for a mere $4,000.00, what a deal! 

For the more "economically challenged" among us, there are a few other options that will allow you to deal with resolving issues with Day light Saving Time updates for Windows 2000.

Option A:  Update your clock Manually
Adjust the system clock manually four times each year:

1. In mid-March, when the new rules start, set forward the clock by one hour.

2. In early-April, when the old rule would have started DST, the clock will need to be set back one hour. This is necessary because the change will already have been made manually three weeks earlier, so the change programmed for April must be cancelled.

3. In late-October, cancel the programmed clock adjustment by setting the clock forward one hour ( DST now runs for an additional week)

4. Finally, in early November when DST now ends, set the clock back one hour.

Option B: Download the tzedit.exe tool using the link under Windows 2000 from the Preparing for daylight saving time changes in 2007 Microsoft web page at http://support.microsoft.com/gp/dst_topissues#A5

Unzip the files into a Windows program directory such as c:\Program Files\TZEdit
1. Exit out of applications.
2. Run the executable tzedit.exe using Start > Run, provide the full path, for example: c:\Program Files\TZEdit\tzedit.exe
3. Your current time zone should be highlighted. Click the Edit button.
4. Set Start Day to Second Sunday, March.
5. Set Last Day to First Sunday, November.
6. Click OK.
7. Click Close

You need to change your time zone twice using the Windows Date and Time Control Panel.
1. From the Start menu, click Settings > Control Panel and then click Date and Time.
2. Click the Time Zone tab.
3. Select a different time zone and click Apply.
4. Now, select your time zone and click Apply, then click OK.
5.Restart your applications.

Daylight Saving Time 2007. why it matters!

Posted by Gerard Louise on Tue, Feb 27, 2007 @ 12:06 PM

The U.S. Energy Policy Act of 2005, passed by the U.S. Congress July, 2005, extended Daylight Saving Time (DST) in the U.S. by approximately four weeks. As a result, beginning in 2007, DST will start three weeks earlier on March 11, 2007, and end one week later on November 4, 2007, resulting in a new DST period that is four weeks longer than previously observed. These four weeks are referred to as the "extended DST period".

Previously DST started on: First Sunday of April (04/01/07) 
New DST will now start this year on: Second Sunday on March (03/11/07)

Previous DST ended on: Last Sunday of October (10/28/2007)
New DST will now end on: First Sunday of November (11/04/07)

Unless certain updates are applied to computers, it is likely that the time zone settings will be incorrect during this four week period. This will of course depends on where you live and which time zone you have selected.

If your time zone settings are incorrect your clock may be off by one hour, and certain applications running on your Windows based computer may not display the correct time.  I don't expect this change in DST to cause serious havoc to most users but it will affect applications that rely on clock settings such as Time and Billing Software, Payroll Applications, Calendaring and Scheduling Software, CRM, etc...

Microsoft and other vendors have issued a series of patches to address this problems and you will find ton of information on the web.  Try to google "DST 2007" and you will see what I mean.  I will save you time with Microsoft and a good place to start is: http://support.microsoft.com/gp/dst_topissues#A
