The documentation is worth reading. I do not share this point of view but would not recommend this utility for general use anyway, because of the following. However, if problem does exist, the utility does not tell you what exactly is going on, and, therefore, you cannot make an intelligent decision what to do. It probably is hard to believe, considering the source and popularity of this utility, but unfortunately is very typical for desktop related Y2K material. RTC and BIOS passed both tests.
Nothing needs to be done.
Both passed Power OFF test. Still do nothing. RTC and BIOS failed rollover to 2000 in both tests, but BIOS accepts 2000 as a valid year. If you are running Windows NT 4.0 - do nothing. BIOS does not accept 2000 as a valid year.
