The PC operating system is reponsible for supplying applications with the
real time and date.

There are a number of ways a program may ask for this information, however
the BIOS RTC call has to be valid to  guarantee that the  time and date is
calculated correctly.

The test included in this software,  checks that both the DOS call and the
BIOS call returns the year correctly in the roll-over to year 2000.

There is no sure method of determining whether a PC is completely compliant
in one easy test as the failure mode is quite vague.   It usually manifests
itself as the date returning to 1980 a few days after roll-over.

Unfortunately,  just  setting  the clock to the correct date again does not
guarantee that it won't fail again a few minutes or even a few days later.

To ensure the PC operating system functions correctly it is imperitive that
the  BIOS  itself  returns  the  date  correctly.   The  Fernlink 2000 Ltd.
Millennium BIOS extension card does this.

Try running the software with and without the card.
