That scenario cannot be thoroughly tested without a Power-Down test now. The question is, can the computer 'remember' the date AND handle a power off, power on sequence. A Power-Down test is hard to provide.
Some companies claim it is unnecessary because circumstances can be mimicked without switching off.
In our opinion this goes against the basic engineering principles of software testing. No one knows how many. The BIOS only works when it is 'called', either at power on, or by a software package asking it for the date. There may be cases when a PC with a software package calling its date directly form the RTC 'rolls over' from 1999 to 2000, while still powered on. There is some debate that the likelihood of this happening is so remote as to negate the need for the test.
