Bug In MSVCRT.DLL

The bug will cause some Windows applications to behave as though it were one hour earlier than the correct time shown on the operating system’s clock. That could lead calendar entries to slip and Windows-based banking systems to record the wrong time for financial transactions.

Microsoft confirmed the bug, but said in most cases a repair would be no problem. “Ninety-nine percent of all packaged applications… can be fixed really simply by downloading a new version, or a patched version, of the DLL”.
