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."
This knowledge base article from Microsoft describes how to use the Time Zone Editor utility (which you can download from that page) to adjust time zone settings.
If you need to update several computers, it also describes which registry keys to export. You can then import those registry keys in a logon script or whatever.
It's not like people/companies running Win2k are SOL.

In the country I live in DST is on a different date every year, and is based on when some
holiday happens to occur in the lunar calendar, so every year in our data centers we either
change the clocks manually, or rely on the Domain Controller on changing the time for
the servers and workstations in the domain.
And we don't complain to Microsoft for not providing us a fix for it.
