Not every computer operating system now running is ready for the automatic switch to Daylight Saving Time (DST) when it arrives on March 11th, 2007. Charles Moore at The Low End Mac discussed the situation, another possible "Y2K" scenario, on Friday.

Mac OS X has been patched to account for the new, earlier change over since version 10.4.6. However, anyone using a previous version, or legacy Mac OS will have to make the adjustment manually.

Steve Wiseman, cofounder of IntelliAdmin, LLC told Mr. Moore, "Microsoft is only providing patches for their supported software. This means that Windows 2000 will not be patched by Microsoft since they no longer support it. We have created an unofficial patch that will fix Windows 2000, and NT systems."
