Millennium Tester Description:

The problem, connected to passing of timers that are
built-in these computers, in some models of computers was
founded of the date of 01.01.2000. These timers do not
increase the counter of centuries. This looks this way:
after 31.12.1999 comes 01.01.1900. Thus, naturally, such
computer after 01.01.2000 will show incorrect date and the
day of the week. Program Millenium Tester solves this problem.
