Unofficial Win2K Daylight Saving Time Fix
Saturn2003a writes "Microsoft has stated that they will not be offering a patch for the new US Daylight Saving Time for Windows 2000 and earlier. Only customers with an extended support agreement can get a Hotfix from Microsoft. To get around this, IntelliAdmin has created an unofficial patch (source code provided) that will fix Daylight Saving Time on Windows 2000 and Windows NT machines."
If an operating system does not define a language for a government agency to express amendments to time zone rules so that the people can download and install patches from a web site operated by the government, then the operating system is broken.
