SYMPTOMS
========

Database is corrupted by file check in operations after the Year 2000 rollover.

CAUSE
=====

A computer has a non-Year 2000 compliant BIOS that causes the system clock to be
reset to an invalid date and time at the year 2000 rollover. Subsequently, when
you check in source code to the Visual SourceSafe (VSS) tree, the date and time
of the computer will be used for the check in of that file. Without a correct
date and time the computer will corrupt the database.

RESOLUTION
==========

Microsoft recommends that all VSS computers BIOS be Year 2000 compliant and
ensure that all client computer clocks are synchronized to the same time. To
ensure this BIOS problem will not affect your VSS database, Microsoft recommends
you make sure these are no files checked out during the date and time at the
year 2000 rollover. Also, make sure that all system clocks have the correct date
and time set before continuing to use the VSS product. Microsoft also strongly
recommends that you backup your VSS database prior to the date and time rollover
at the end of 1999.

STATUS
======

This behavior is by design.

MORE INFORMATION
================

Because VSS is not a client server architecture, all Source Code Control
functions are performed on the computer. With this design, clocks that are not
synchronized can cause inconsistent history data especially on files marked for
shared checkout.
