TITLE   :Mfc40.dll Causes Programs to Display Wrong Date After 01/01/2000
PRODUCT :Microsoft Windows NT
PROD/VER:winnt:4.0
OPER/SYS:
KEYWORDS:

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Windows NT Server version 4.0 
 - Microsoft Windows NT Workstation version 4.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

An internal function within Mfc40.dll is designed to add 1900 to every 2-digit
date that is passed to it. For example, 99 is returned as 1999. If more than 2
digits are passed, nothing is added. Programs that use this function may
incorrectly parse a date after the year 2000 (for example, January 1, 2000, may
become January 1, 100).

This problem has been observed with the following applications:

 - Microsoft System Information (Msinfo32.exe)

3. Start Msinfo32.exe (version: 4.10.1998) of Windows 98. (Msinfo32.exe is

4. On the File menu, click Save, specify a file name, and then click Save.

5. Start Windows Explorer, right-click the file created in step 4, and click
