Update for 2009:

We have updated our free DST patch for Windows NT, 2000, 2003 and XP. You don’t need it for Vista, 2008, or Windows 7 since Microsoft still supports those operating systems

For Windows XP, you only need it if you don’t want to be forced to upgrade to the latest service pack, and 2000 and NT, you need it if you want your time to be right. There were a few changes across the world since last year, so we have released an update

You can download the free application from here:

You can use Network Administrator to deploy it across your network, since it has the updated settings too:

Post from 2007 Continues below:

You may have forgotten by now, but two years ago the US government changed the dates for daylight saving time. When the law was passed it was set to take effect in 2007.

Well, here we are. It is 2007, and Microsoft has published updates for XP, and 2003. But…No update for 2000 Workstation, or any of the server editions.

This is a huge problem for many organizations. I know some companies that have hundreds of Windows 2000 boxes. The thought that they will need to upgrade to XP or 2003 (Just for this) is a nightmare. Microsoft is providing a hotfix – but only to the companies that have an extended support contract. To their credit, Microsoft does provide a registry workaround for the rest of us.

The workaround that Microsoft provides is not easy to follow. Check out the KB article at Microsoft.

We have created a utility that will update any machine to the new daylight saving format (XP, NT, 2000, 2003, Vista). Obviously you only need it for 2000, or NT since those operating systems have dropped off support.

It updates Daylight Saving Time (Yes it is Saving, not Savings) in these time zones:

-Alaska Standard Time Zone
-Central Standard Time Zone
-Eastern Standard Time Zone
-Mountain Standard Time Zone
-Pacific Standard Time Zone
-Atlantic Standard Time Zone (Canada)
-Newfoundland Standard Time Zone (Canada)

If we are missing another US timezone that supports daylight saving time, please let us know by emailing support@intelliadmin.com

The utility can install, or uninstall the change. It runs without any setup and requires no extra DLLs or runtime. It is less than 1mb, so you can put it on a flash drive:

It can run silently from the command line if you use these options:

Install:

DaylightSavingFix.exe /qinstall

UnInstall:

DaylightSavingFix.exe /quninstall

Please note that the program must be run as administrator since it access HKEY_LOCAL_MACHINE

If you want to roll it out to multiple machines we have updated our Network Administrator product to install the patch.

Both can be downloaded from our downloads section
