SYMPTOMS
When the system clock is set to any date and time after January 18, 2038 at 19:14:07, loading the Microsoft Visual C++ development environment fails with an application error or a general protection (GP) fault, and execution terminates.



CAUSE
The C Run-time (CRT) has a limitation with the time/date functions. Time is measured in seconds from January 1, 1970. This value is a 32-bit signed integer. Therefore, this value has a maximum date of Jan 18, 2038 19:14:07 or 2^31 seconds (2,147,483,648 seconds) from Jan 1, 1970 00:00:00. Because the development environment depends on time/date routines from the CRT, the time functions will fail and cause the error.



RESOLUTION
Make sure that the system date is set correctly before January 18, 2038.



STATUS
Microsoft has confirmed that this is a bug in the Microsoft products that are listed in the "Applies to" section. This bug was corrected in Microsoft Visual C++, version 6.0.
