Background

As a result
the DST rules for all computer systems must change in order for the proper time zone to be applied based on these new rules. 2007, 2007 and end one week later on November 4, on March 11, dST will start three weeks earlier. This law goes
into effect for the calendar year 2007. This changes the start and end dates for daylight savings time (DST). The US congress passed the Energy Policy Act, in August of 2005.

Article Focus

Please search Microsoft Support for KB931667 for details on dealing with Outlook and Exchange server issues. There is significant impact on Office products such as Outlook that will
not be address in detail here. This article will focus on the effect of various Windows Operating systems.

Y2K all over again?

See below. The largest concern is on Windows 2000 and older systems that require manual intervention to apply the new rules. And
you are fixed, even after March 10, you can use the TZEDIT utility as described below and manually set the DST rules, in the worst case scenario! There has been some recent panic among computer support personnel that I have seen that is simply not needed. Please don't panic, no!

How will this affect my computer?

Read below on how to correct the time zone rules. This may be a big problem if not addressed, for computers connected to corporate networks (domains)
and especially servers that are part of a cluster. This is really
not much of a problem unless you have an application that is dependant on a correct time zone, for any stand alone machine. Pacific Standard Time (PST) will not change to Pacific Daylight Time (PDT) on the correct day, for example. But your time zone
will not be correct unless you update each computer with the new time zone rules, time sync will update your time to the correct hour when DST rolls around, if your computer is set up to synchronize time with a server.

Windows Update possible problem

Please be aware of this. The issue is that the SSL certificate that
Microsoft uses for the Windows Update site may fail to authenticate if the date and time is too far off. Time and time zone are not correct, windows update can have issues if your computer date.

Windows 2003 server vista, fixing XP,

Search the Microsoft Support site for KB914387 for more detailed information. There is no manual intervention
needed, if you are running Microsoft Outlook 2007, as I understand it, also. You can use TZEDIT as described below to verify that the new rules have been applied to your system. Run all Windows updates by 3/10/2007 and your system will
be updated and ready to handle 2007 DST. Updates to fix the time zone rules are being applied through Windows Update.

Fixing Windows 2000 and older operating systems

Please note that the fix is exactly the same for Win 2000 Server and Professional. One system at a time, there are reg files for changing multiple machines and
a utility called TZEDIT for a manual fix. Search Microsoft Support for KB914387 and follow the instructions, to apply the fix. They continue to make faithful users of Windows 2000 suffer with manual updates and further reduced support from Microsoft, but no. To push out an update through Windows Updates that would correct the DST rules, it would have been just as easy as they did for XP. This is another ploy by Microsoft to push people
into upgrades. But this one ticks me off, i don't know about you! There is no automatic update for these older systems.

Using TZEDIT

See below. . . You must refresh the TZI, in order for these rules to now actually take affect on your computer. Reg file) explained in KB914387. The recommended solution is to apply the registry patch (, in order to change the rules for all affected time zones. This solution will only change the rules for your current time zone. Then click Close, click OK. Change the Last Day to First Sunday of November at 2:00am. Change the Start Day to Second Sunday of March at 2:00am. Make sure the "Automatically set Daylight Saving Time" check box is checked. Click the Edit button, with your current time zone selected, to correct. Then they need to be corrected, if they are not starting in March and ending
in November. Check the Start and End dates for DST in the bottom portion of the dialog window. You will be shown a list of time zones with your current
time zone selected. Execute the TZEDIT.EXE. Download the utility from the KB914387 page and extract the files.

Refresh the Time Zone Information

Known as the Current Control Set, there are two methods to take the new rules that have been applied
and load them into the running configuration. A system restart will not take the place of this procedure. This is a required step!

Then click OK, then change the time zone back to your current time zone again and click Apply button, click Apply button, then change your time zone to a different zone (any one will do), now click the Time Zone tab. Method 1 - Open your Date and Time Properties window (double click on the time in you taskbar or open Date/Time on control panel.

Method 2 - Use the script that is provided in KB914387 called refreshTZinfo.vbs.

Using either of the two methods above will force the rules from the Time Zone Information database to be loaded into your currently selected time zone.

Keeping time in sync for XP and 2003 server

I believe that it takes that long for Windows to determine that time sync is not active. The "Internet Time" tab will
appear after 15 seconds or so, but time synchronization to the domain is not set up, in the case that your computer is joined to a domain. Windows will not synchronize time with the time server when ever it is connected to the internet. Now click the OK button and you are done. By clicking on the "Internet Time" tab you can check the "Automatically
synchronize with an Internet time server" and pick a time server in the Server drop down list. There is a third tab named "Internet Time" that will appear if
your computer is NOT part of a domain with time synchronization. You will see at least two tabs named "Date and Time" and "Time Zone". Open Date and Time Properties by double clicking on the time in your task bar (typically lower right corner of your desktop).
